TACHA, Chief Circuit Judge.
Hornbook constitutional law provides that if Oklahoma wants to limit the sale of caskets to licensed funeral directors, the Equal Protection Clause does not forbid it. See Fitzgerald v. Racing Assoc. of Cent. Iowa, 539 U.S. 103, 109, 123 S.Ct. 2156, 156 L.Ed.2d 97 (2003) (holding that the Equal Protection Clause does not prohibit Iowa’s differential tax rate favoring the intrastate racetrack over the intrastate riverboat gambling industry); Ferguson v. Skrupa, 372 U.S. 726, 732-33, 83 S.Ct. 1028, 10 L.Ed.2d 93 (1963) (“If the State of Kansas wants to limit debt adjusting to lawyers, the Equal Protection Clause does not forbid it.”). Plaintiff-Appellants Kim Powers, Dennis Bridges, and Memorial Concepts Online, Inc. (collectively “Plaintiffs”), who wish to sell caskets over the Internet without obtaining the licenses required by Oklahoma law, challenge the soundness of this venerable rule. Seeking declaratory relief, Plaintiffs sued Defendant-Appellees, who are members of the Oklahoma State Board of Embalmers and Funeral Directors (“the Board”), the relevant licensing authority. After a full bench trial, the District Court ruled for the Board. On appeal, Plaintiffs contend that Oklahoma’s licensing scheme violates the Privileges and Immunities, Due Process, and Equal Protection clauses of the Fourteenth Amendment to the Federal Constitution. We take jurisdiction pursuant to 28 U.S.C. § 1291 and AFFIRM.
I. BACKGROUND
The Oklahoma Funeral Services Licensing Act, Okla. Stat. tit. 59, § 395.1 et seq. (“FSLA”), and Board rules promulgated pursuant to the FSLA provide the regulatory scheme for the funeral industry in Oklahoma. Pursuant to the FSLA, any person engaged in the sale of funeral-service merchandise,1 including caskets, must be a licensed funeral director2 operating out of a funeral establishment.3 Id. at § 396.3a; see also id. at § 396.6(A) [1212]*1212(prohibiting sale of funeral merchandise without a license).4
Oklahoma does not, however, apply this licensing requirement to those who sell other funeral-related merchandise (e.g., urns, grave markers, monuments, clothing, and flowers). Furthermore, because the Board distinguishes between time-of-need and pre-need sales,5 this licensing requirement does not apply to all casket sales.6 Specifically, although a person must be fully licensed to make time-of-need sales,7 a salesperson may lawfully sell caskets pre-paid without a license so long as that person is acting as an agent of a licensed funeral director.
Finally, while the Board may issue orders to enforce the FSLA, see id. at § 396.2a, the FSLA limits its enforcement to intrastate casket sales only, Dist. Ct. Op. at 3 (finding of fact). As such, an unlicensed Oklahoman may sell a time-of-need casket to a customer outside of Oklahoma — indeed, Plaintiffs have sold caskets to consumers located outside of Oklahoma — and an unlicensed salesperson who is not located in Oklahoma may sell a time-of-need casket to a customer in Oklahoma. The requirement that a salesperson possess both a funeral director’s license and operate out of a licensed funeral establishment applies, therefore, only to the intrastate sale of time-of-need caskets in Oklahoma.
Obtaining these licenses is no small feat. According to the Board’s rules, an applicant for a funeral director’s license must complete both sixty credit hours of specified undergraduate training8 and a one-year apprenticeship during which the applicant must embalm twenty-five bodies. An applicant also must pass both a subject-matter and an Oklahoma law exam. See generally Okla. Admin. Code §§ 235:10-1-2, 10-3-1. Furthermore, to be licensed as a funeral establishment in Oklahoma, a business must have a fixed physical location, a preparation room that [1213]*1213meets the requirements for embalming bodies, a funeral-service merchandise-selection room with an inventory of not less than five caskets, and adequate areas for public viewing of human remains. See generally id. at §§ 235:10-1-2, 10-3-2. In reflecting on these legislative and administrative regulations, the District Court concluded that “they evince an intent to fore-go laissez faire treatment of those sales and services when provided in this State. Limiting the sale of caskets to sellers licensed by the Board is, undeniably, a major component of that statutory scheme.” Dist. Ct. Op. at 13.
Memorial Concepts Online, Inc. is an Oklahoma corporation created, operated, and owned by Ms. Powers and Mr. Bridges to sell funeral merchandise over the Internet.9 It offers no other death- or funeral-related services, plays no role in the disposition of human remains, and is not licensed in Oklahoma as a funeral establishment. Although Ms. Powers, who lives in Ponca City, Oklahoma, has many years of experience selling caskets on a pre-need basis as the agent of a licensed Oklahoma funeral director, she is not licensed by the Board as either a funeral director or as an embalmer. Likewise, although Mr. Bridges has been a licensed funeral director in Tennessee for over twenty years, he is not licensed in Oklahoma. As a part of their current enterprise, Plaintiffs wish to sell in-state, time-of-need caskets to Oklahomans over the Internet.10 They have foregone these sales because they “have a reasonable and genuine fear that if they were to sell caskets to Oklahoma consumers, they might be prosecuted for violation of the FSLA and Board rules.” Dist. Ct. Op. at 3.
Importantly, Plaintiffs have no desire to obtain the appropriate Oklahoma licenses because they view their requirements as irrelevant to the operation of an intrastate, Internet, retail, casket business. On this point, the District Court specifically found that
very little specialized knowledge is required to sell caskets. Most consumers select caskets based on price and style. Any information a generally educated person needs to know about caskets in order to sell them can be acquired on the job. Less than five per cent of the [1214]*1214education and training requirements necessary for licensure in Oklahoma pertain directly to any knowledge or skills necessary to sell caskets. As a result of the substantial misfit between the education and training required for licensure and the education and training required to sell caskets in Oklahoma, people who only wish to sell caskets, if they wish to make in-state sales, are required to spend years of their lives equipping themselves with knowledge and training which is not directly relevant to selling caskets. Dist. Ct. Op. at 5.
Thus, Plaintiffs brought this declaratory judgment action, asserting that the FSLA violates the Privileges and Immunities, Due Process, and Equal Protection clauses of the Fourteenth Amendment to the United States Constitution.11 After a thorough bench trial, the District Court, in its well-reasoned order and memorandum, found for the Board on all counts. Plaintiffs filed a timely notice of appeal.
II.STANDARD OF REVIEW
“We review challenges to the constitutionality of a statute de novo.” United States v. Plotts, 347 F.3d 873, 877 (10th Cir.2003) (quotations omitted). We review the District Court’s factual findings for clear error. Fed.R.Civ.P. 52(a).
III.PRIVILEGES AND IMMUNITIES CLAUSE
Plaintiffs contend that the FSLA violates the Privileges and Immunities Clause of the Fourteenth Amendment. U.S. Const, amend. XIV, § 1 (“No State shall make or enforce any law which shall abridge the privileges and immunities of citizens of the United States[.]”). Citing Saenz v. Roe, 526 U.S. 489, 119 S.Ct. 1518, 143 L.Ed.2d 689 (1999), they contend that “the right to earn an honest living ... [is found] in the Privileges and Immunities Clause.” Aplt. Brief at 62. Despite Plaintiffs’ protestations, Saenz does not mark a sea change in long-standing constitutional jurisprudence. As such, we agree with the District Court’s disposition of this claim: “There is no merit to this ground for challenge. Revival of the Privileges and Immunities Clause may be an interesting and useful topic for scholarly debate but this memorandum is not the place for that discussion.” Dist. Ct. Op. at 8 (citations omitted). To the extent that Plaintiffs argue that we should overrule the Slaughter-House Cases, 83 U.S. (16 Wall.) 36, 21 L.Ed. 394 (1872), it is enough to remind Plaintiffs that “it is [the Supreme] Court’s prerogative alone to overrule one of its precedents.” State Oil Co. v. Khan, 522 U.S. 3, 20, 118 S.Ct. 275, 139 L.Ed.2d 199 (1997); but see Saenz, 526 U.S. at 521, 119 S.Ct. 1518 (Thomas, J., dissenting) (urging the Court to reconsider its privileges-and-immunities jurisprudence).
IV.DUE PROCESS AND EQUAL PROTECTION CLAUSES
Plaintiffs next contend that the FSLA violates two rights under the Fourteenth Amendment. First, they claim, as a matter of substantive due process, that the FSLA violates “the right of every citizen of the United States to follow any lawful calling, business, or profession he may choose[.]” Dent v. West Virginia, 129 U.S. 114, 121, 9 S.Ct. 231, 32 L.Ed. 623 (1889) (upholding West Virginia’s physician licensing scheme against a substantive due [1215]*1215process challenge). Second, they contend, as a matter of equal protection, that the FSLA is unconstitutional because the Board is “arbitrarily treating similarly-situated people differently, and ... arbitrarily treating differently-situated people the same.” Aplt. Brief at 24. As a state economic regulation that does not affect a fundamental right and categorizes people on the basis of a non-suspect classification, we determine whether the FSLA passes constitutional muster, both as a matter of substantive due process and equal protection, by applying rational-basis review. See Fitzgerald, 539 U.S. at 107, 123 S.Ct. 2156 (equal protection); General Motors Corp. v. Romein, 503 U.S. 181, 191, 112 S.Ct. 1105, 117 L.Ed.2d 328 (1992) (substantive due process).
A. Equal Protection Versus Substantive Due Process
Because their substantive analyses converge, often the differences between equal protection and substantive due process are not fully appreciated. The Equal Protection and Due Process clauses protect distinctly different interests. On the one hand, the “substantive component” of the Due Process Clause “provides heightened protection against government interference with certain fundamental rights and liberty interests,” Washington v. Glucksberg, 521 U.S. 702, 720, 117 S.Ct. 2258, 138 L.Ed.2d 772 (1997), even when the challenged regulation affects all persons equally. In contrast, “the essence of the equal protection requirement is that the state treat all those similarly situated similarly,” Bartell v. Aurora Pub. Schs., 263 F.3d 1143, 1149 (10th Cir.2001) (quotations omitted), with its “central purpose [being] the prevention of official conduct discriminating on the basis of race [or other suspect classifications,]” Washington v. Davis, 426 U.S. 229, 239, 96 S.Ct. 2040, 48 L.Ed.2d 597 (1976). As such, equal protection only applies when the state treats two groups, or individuals, differently-
Here, Plaintiffs have cast their challenge to the FSLA as both a substantive due process and an equal protection claim. Although Plaintiffs forward both contentions, their challenge is most properly presented as an equal protection claim, as evidenced by the fact that they almost exclusively cite to equal protection cases (even to support their substantive due process argument) and that the Court itself has most often analyzed regulatory challenges under the equal protection rubric. In any event, because a substantive due process analysis proceeds along the same lines as an equal protection analysis, our equal protection discussion sufficiently addresses both claims.
B. Parties ’ Arguments
To satisfy the rational basis test, “the [FSLA] need only be rationally related to a legitimate government purpose.” Save Palisade FruitLands v. Todd, 279 F.3d 1204, 1210 (10th Cir.2002). The Board argues that protecting casket purchasers, a particularly vulnerable group, constitutes a legitimate state interest. Plaintiffs concede this point, and we agree as well. See Turner Broad. Sys. v. FCC, 520 U.S. 180, 189-90, 117 S.Ct. 1174, 137 L.Ed.2d 369 (1997) (finding consumer protection a legitimate federal governmental interest in a First Amendment challenge). Thus, as framed by the parties, the relevant question is whether the FSLA’s licensure scheme is rationally related to the state’s proffered consumer protection interest.
Plaintiffs contend that it is not. They argue that the regulatory scheme is irrational because “[l]ess than five per cent of the education and training requirements necessary for licensure in Oklahoma pertain directly to any knowledge or skills [1216]*1216necessary to sell caskets[.]” Dist. Ct. Op. at 5; see also Cornwell v. Hamilton, 80 F.Supp.2d 1101, 1111 (S.D.Cal.1999) (holding California’s cosmetology licensing requirements in violation of the Fourteenth Amendment’s Due Process and Equal Protection clauses because “just over six percent of the curriculum is relevant .... [to] a would-be African hair braider”). Indeed, Plaintiffs claim that “every single federal court ... that has considered casket sales restrictions like Oklahoma’s has found they lack any rational basis.”12 Aplt. Brief at 23.
The Board concedes that its licensure requirements do not perfectly match its asserted consumer-protection goal. Instead, they contest the degree of fit needed to pass rational-basis review. In the Board’s view, “[a] statutory classification fails rational-basis review only when it rests on grounds wholly irrelevant to the achievement of the State’s objective.” Heller v. Doe by Doe, 509 U.S. 312, 324, 113 S.Ct. 2637, 125 L.Ed.2d 257 (1993) (quotations omitted) (emphasis added). The Board further contends that:
[t]hese restraints on judicial review have added force where the legislature must necessarily engage in a process of line-drawing. Defining the class of persons subject to a regulatory requirement ... inevitably requires that some persons who have an almost equally strong claim to favored treatment be placed on different sides of the line, and the fact [that] the line might have been drawn differently at some points is a matter for legislative, rather than judicial, consideration .... This necessity renders the precise coordinates of the resulting legislative judgment virtually unreviewable, since the legislature must be allowed leeway to approach a perceived problem incrementally. FCC v. Beach Communications, Inc., 508 U.S. 307, 315-16, 113 S.Ct. 2096, 124 L.Ed.2d 211 (1993) (internal citations and quotations omitted).
The Board urges that its licensing protocol is not “wholly irrelevant” because “[e]very witness who testified on the subject agreed that consumers purchasing time-of-need caskets may be especially vulnerable to overreaching sales tactics because of grief and other emotions which arise as the result of the death of the person for whom the consumer is purchasing a casket.” Dist. Ct. Op. at 5. The Board further notes that “[e]ven [Plaintiffs’] own expert, Lisa Carlson, admitted that Oklahoma’s FSLA functions to protect consumers and that removing those provisions would effectively reduce consumer protection for people buying caskets in ... Oklahoma.” Aple. Brief at 22.
C. Equal Protection and Judicial Review of Economic Legislation
In United States v. Carolene Products Co., 304 U.S. 144, 154, 58 S.Ct. 778, 82 L.Ed. 1234 (1938), the Court held, pursuant to rational basis review, that when legislative judgment is called into question on equal protection grounds and the issue is debatable, the decision of the [1217]*1217legislature must be upheld if “any state of facts either known or which could reasonably be assumed affords support for it.” Second-guessing by a court is not allowed. Id.; see also Beach Communications, 508 U.S. at 313, 113 S.Ct. 2096 (“[E]qual protection analysis is not a license for courts to judge the wisdom, fairness, or logic of legislative choices.”); New Orleans v. Dukes, 427 U.S. 297, 303, 96 S.Ct. 2513, 49 L.Ed.2d 511 (1976) (per curiam) (“The judiciary may not sit as a super legislature to judge the wisdom or desirability of legislative policy determinations made in areas that neither affect fundamental rights nor proceed along suspect lines.... ”).
Further, rational-basis review does not give courts the option to speculate as to whether some other scheme could have better regulated the evils in question. Mourning v. Family Publ’n Serv., Inc., 411 U.S. 356, 378, 93 S.Ct. 1652, 36 L.Ed.2d 318 (1973). In fact, we will not strike down a law as irrational simply because it may not succeed in bringing about the result it seeks to accomplish, Seagram & Sons, Inc. v. Hostetter, 384 U.S. 35, 50, 86 S.Ct. 1254, 16 L.Ed.2d 336 (1966), abrogated on other grounds by Healy v. Beer Inst., Inc., 491 U.S. 324, 342, 109 S.Ct. 2491, 105 L.Ed.2d 275 (1989), or because the statute’s classifications lack razor-sharp precision, Dandridge v. Williams, 397 U.S. 471, 485, 90 S.Ct. 1153, 25 L.Ed.2d 491 (1970). Nor can we overturn a statute on the basis that no empirical evidence supports the assumptions underlying the legislative choice. Vance v. Bradley, 440 U.S. 93, 110-11, 99 S.Ct. 939, 59 L.Ed.2d 171 (1979).
Finally, “because we never require a legislature to articulate its reasons for enacting a statute, it is entirely irrelevant for constitutional purposes whether the conceived reason for the challenged distinction actually motivated the legislature.” Beach Communications, 508 U.S. at 315, 113 S.Ct. 2096 (citations and quotations omitted). “[T]hose attacking the rationality of the legislative classification have the burden ‘to negative every conceivable basis which might support it[.]’ ” Id. (quoting Lehnhausen v. Lake Shore Auto Parts Co., 410 U.S. 356, 364, 93 S.Ct. 1001, 35 L.Ed.2d 351 (1973)); see also McDonald v. Board of Election Comm’rs, 394 U.S. 802, 809, 89 S.Ct. 1404, 22 L.Ed.2d 739 (1969) (“Legislatures are presumed to have acted constitutionally even if source materials normally resorted to for ascertaining their grounds for action are otherwise silent, and their statutory classifications will be set aside only if no grounds can be conceived to justify them.”). As such, we are not bound by the parties’ arguments as to what legitimate state interests the statute seeks to further. In fact, “this Court is obligated to seek out other conceivable reasons for validating [a state statute.]” Starlight Sugar, Inc. v. Soto, 253 F.3d 137, 146 (1st Cir.2001) (emphasis added). Indeed, that the purpose the court relies on to uphold a state statute “was not the reason provided by [the state] is irrelevant to an equal protection inquiry.” Id. (citing Beach Communications, 508 U.S. at 315, 113 S.Ct. 2096).13
[1218]*1218These admonitions are more than legal catch phrases dutifully recited each time we confront an equal protection challenge to state regulation — they make sense. First, in practical terms, we would paralyze state governments if we undertook a probing review of each of their actions, constantly asking them to “try again.” Second, even if we assumed such an exalted role, it would be nothing more than substituting our view of the public good or the general welfare for that chosen by the states. As a creature of politics, the definition of the public good changes with the political winds. There simply is no constitutional or Platonic form against which we can (or could) judge the wisdom of economic regulation. Third, these admonitions ring especially true when we are reviewing the regulatory actions of states, who, in our federal system, merit great respect as separate sovereigns. See generally Geier v. American Honda Motor, Inc., 529 U.S. 861, 894, 120 S.Ct. 1913, 146 L.Ed.2d 914 (2000).
Thus, we are obliged to consider every plausible legitimate state interest that might support the FSLA — not just the consumer-protection interest forwarded by the parties. Hence, we consider whether protecting the intrastate funeral home industry, absent a violation of a specific constitutional provision or a valid federal statute, constitutes a legitimate state interest. If it does, there can be little doubt that the FSLA’s regulatory scheme is rationally related to that goal. See Craigmiles v. Giles, 312 F.3d 220, 228 (6th Cir.2002) (stating that Tennessee’s version of the FSLA is “very well tailored” to “protecting licensed funeral directors from competition on caskets”).
D. Intrastate Economic Protectionism
Implicit in Plaintiffs’ argument is the contention that intrastate economic protectionism, even without violating a specific constitutional provision or a valid federal statute, is an illegitimate state interest. See Aplt. Brief at 53 n.8. Indeed, Plaintiffs describe Oklahoma’s licensure scheme as “a classic piece of special interest legislation designed to extract monopoly rents from consumers’ pockets and funnel them into the coffers of a small but politically influential group of business people— namely, Oklahoma funeral directors.” Id. at 26. Amici are not so coy. In their view, Oklahoma’s licensure scheme “is simply ... protectionist legislation^]” Brief of Amicus Curiae Claremont Institute at 26, and “[u]nder the Constitution, ... economic protectionism is not a legitimate state interest!,]” Brief of Amicus Curiae Pacific Legal Foundation at 2.
By our count, only three courts have held, in the absence of a violation of a specific constitutional provision or a valid federal statute, that “protecting a discrete interest group from economic competition is not a legitimate governmental purpose.” Craigmiles, 312 F.3d at 224;14 see also Cornwell, 80 F.Supp.2d at 1117 (implying, without citation, that establishing a cartel for cosmetology services is not a legitimate state interest); Santos v. City of Houston, 852 F.Supp. 601, 608 (S.D.Tex.1994) (holding that “economic protectionism in its most glaring form ... [is] not legitimate.”).15 Because the four Supreme Court cases collectively cited by Craig-[1219]*1219miles and Santos do not stand for the proposition that intrastate economic protectionism, absent a violation of a specific constitutional provision or federal statute, is an illegitimate state interest, we cannot agree.
In fact, it is only by selective quotation that such a reading of these Supreme Court cases appears plausible. For example, in H.P. Hood & Sons, Inc., v. DuMond, 336 U.S. 525, 69 S.Ct. 657, 93 L.Ed. 865 (1949), the Court considered whether “the State of New York [had the power] to deny additional facilities to acquire and ship milk in interstate commerce where the grounds of denial are that such limitation upon interstate business will protect and advance local economic interests.” Id. at 526, 69 S.Ct. 657 (emphasis added). The Court struck the legislation. The Craigmiles court cites to the following passage from H.P. Hood & Sons, which is clearly limited to the regulation of interstate commerce, to support its conclusion that intrastate economic protectionism is an illegitimate state interest:
This principle that our economic unit is the Nation, which alone has the gamut of powers necessary to control of the economy, including the vital power of erecting customs barriers against foreign competition, has as its corollary that the states are not separable economic units. As the Court said in Baldwin v. G.A.F. Seelig, Inc., 294 U.S. 511, 527, 55 S.Ct. 497, 79 L.Ed. 1032, “What is ultimate is the principle that one state in its dealings with another may not place itself in a position of economic isolation.’ In so speaking it but followed the principle that the state may not use its admitted powers to protect the health and safety of its people as a basis for suppressing competition. In Buck v. Kuykendall, 267 U.S. 307, 45 S.Ct. 324, 69 L.Ed. 623, the Court struck down a state act because, in the language of Mr. Justice Brandeis, ‘Its primary purpose is not regulation with a view to safety or to conservation of the highways, but the prohibition of competition.’ The same argument here advanced, that limitation of competition would itself contribute to safety and conservation, and therefore indirectly serve an end permissible to the state, was there declared ‘not sound.’ It is no better here. This Court has not only recognized this disability of the state to isolate its own economy as a basis for striking down parochial legislative policies designed to do so, but it has recognized the incapacity of the state to protect its own inhabitants from competition as a reason for sustaining particular exercises of the commerce power of Congress to reach matters in which states were so disabled. H.P. Hood & Sons, 336 U.S. at 537-38, 69 S.Ct. 657 (citations omitted).
When read in context, H.P. Hood & Sons’s admonition is plainly directed at state regulation that shelters its economy from the larger national economy, i.e., violations of the “dormant” Commerce Clause.
The other cases relied upon in Craigmiles and Santos are similarly distinguishable. See Energy Reserves Group, Inc. v. Kansas Power & Light Co., 459 U.S. 400, 103 S.Ct. 697, 74 L.Ed.2d 569 (1983) (addressing a Contracts Clause-specific issue); Minnesota v. Clover Leaf Creamery Co., 449 U.S. 456, 471, 101 S.Ct. 715, 66 L.Ed.2d 659 (1981) (addressing the “dormant” Commerce Clause); City of Philadelphia v. New Jersey, 437 U.S. 617, 618, 98 S.Ct. 2531, 57 L.Ed.2d 475 (1978) (addressing whether “[a] New Jersey law prohibit[ing] the importation of most solid or liquid waste which originated or was collected outside the territorial limits of the State .... violates the Commerce Clause of the United States Constitution.”). As such, these passages do not support the contention espoused in Craig-miles and Santos that intrastate economic [1220]*1220protectionism, absent a violation of a specific federal statutory or constitutional provision, represents an illegitimate state interest. Our country’s constitutionally enshrined policy favoring a national marketplace is simply irrelevant as to whether a state may legitimately protect one intrastate industry as against another when the challenge to the statute is purely one of equal protection. See Metropolitan Life Ins. Co. v. W.G. Ward, 470 U.S. 869, 105 S.Ct. 1676, 84 L.Ed.2d 751 (1985) (noting that the Commerce Clause and the Equal Protection Clause “perform different functions in the analysis of the permissible scope of a state’s power — one protects interstate commerce, and the other protects persons from unconstitutional discrimination by states”).
In contrast, the Supreme Court has consistently held that protecting or favoring one particular intrastate industry, absent a specific federal constitutional or statutory violation, is a legitimate state interest. See Fitzgerald, 539 U.S. at 109, 123 S.Ct. 2156 (holding that the hypothetical goal of fostering intrastate riverboat gambling provided a rational basis to support legislation taxing riverboat slot machine revenues at a more favorable rate than those from racetrack slot machines); Ferguson, 372 U.S. at 730-31, 83 S.Ct. 1028 (“It is now settled that States have power to legislate against what are found to be injurious practices in their internal commercial and business affairs, so long as their laws do not run afoul of some specific federal constitutional prohibition, or of some valid federal law.”) (quotations omitted); Dukes, 427 U.S. at 304 n. 5, 96 S.Ct. 2513 (“[T]hese principles ... govern only when no constitutional provision other than the Equal Protection Clause itself is apposite. Very different principles govern even economic regulation when constitutional provisions such as the Commerce Clause are implicated, or when local regulation is challenged under the Supremacy Clause as inconsistent with relevant federal laws or treaties.”).
The Court’s application of this principle is found in numerous state subsidization and licensing equal protection cases. For example, in Fitzgerald, the Court held that an Iowa statute taxing slot machine revenues on riverboats at 20 %, while taxing those at racetracks at 36 %, did not violate the Equal Protection Clause because, even though they harmed the racetracks, “the different tax rates” may have furthered the state’s legitimate interest in “help[ing] the riverboat industry.” 539 U.S. at 110, 123 S.Ct. 2156. More specifically, the Fitzgerald Court held:
Once one realizes that not every provision in a law must share a single objective, one has no difficulty finding the necessary rational support for the 20 percent/36 percent [tax] differential here at issue. That difference, harmful to the racetracks, is helpful to the riverboats, which, as respondents concede, were also facing financial peril. These two characterizations are but opposite sides of the same coin. Each reflects a rational way for a legislator to view the matter. Id. at 109, 123 S.Ct. 2156 (citations omitted).
Indeed, even Plaintiffs concede that “the [Fitzgerald ] Court found [helping the riverboat industry] to be [a] legitimate governmental objective[.]” Aplt. Reply Brief at 6.
In Nordlinger v. Hahn, 505 U.S. 1, 18, 112 S.Ct. 2326, 120 L.Ed.2d 1 (1992), the Court held that California’s property taxation scheme, which favored long-time property holders over new purchasers, did not violate the Equal Protection Clause. In discussing the many possible reasons for the taxation scheme, the Court held that “[t]he State ... legitimately can decide to ... [favor] established, ‘mom-and-pop’ businesses ... [over] newer chain operations.” Id. at 12, 112 S.Ct. 2326.
[1221]*1221In Dukes, the Court rejected an Equal Protection Clause challenge to a New Orleans ordinance that prohibited selling foodstuffs from pushcarts in the French Quarter, even though it exempted area vendors who had continuously operated that business for eight or more years. 427 U.S. at 298, 96 S.Ct. 2513. This ordinance had the effect of allowing only two vendors to continue operation in the French Quarter. Id. at 300, 96 S.Ct. 2513. Although the court of appeals struck the legislation as furthering an illegitimate state purpose because the ordinance created “a protected monopoly for the favored class memberf,]” id. (quotations omitted), the Court rejected this reasoning, id. at 303, 96 S.Ct. 2513. Instead, it found that the ordinance furthered a legitimate state purpose, because the presence of “vendors in the [French Quarter], the heart of the city’s tourist industry, might ... have a deleterious effect on the economy of the city.” Id. at 304-05, 96 S.Ct. 2513. As the Court noted, “[t]he legitimacy of that objective [, i.e., benefitting the tourist industry,] is obvious.” Id. at 304, 96 S.Ct. 2513.
Finally, in the watershed Equal Protection Clause case of Williamson v. Lee Optical of Oklahoma, 348 U.S. 483, 75 S.Ct. 461, 99 L.Ed. 563 (1955), the Court held that a state may set as a legitimate goal “free[ing a] profession, to as great an extent as possible, from all taints of commercialism.” 348 U.S. at 491, 75 S.Ct. 461. Indeed, Williamson so closely mirrors the facts of this case that, but for the Siren’s song that has recently induced other courts to strike state economic legislation similar to the FSLA, merely a citation to Williamson would have sufficed to dispose of this case.16
Similarly, the Tenth Circuit has held that state legislation granting special benefits to an intrastate industry, absent a specific federal constitutional or statutory violation, does not run afoul of the Equal Protection Clause. For example, in Schafer v. Aspen Skiing Corp., 742 F.2d 580, 583 (10th Cir.1984), an injured party pursued an equal protection challenge to Colorado’s special three-year statute of limitations that applied only to suits against the ski industry. In rejecting the challenge, we noted that “[t]he ski industry makes a substantial contribution, directly or indirectly, to the Colorado economy” and that the “state has a legitimate interest in its well-being and economic viability.” Id. at 584. Although the plaintiff in Schafer was an injured consumer and not a competitor, the underlying principle holds true: favoring one intrastate industry over another is a legitimate state interest. In short, given the overwhelming supporting authority, and the dearth of credible arguments to the contrary, we hold that, absent a violation of a specific constitutional provision or other federal law, intrastate economic protectionism constitutes a legitimate state interest.
We also note, in passing, that while baseball may be the national pastime of the citizenry, dishing out special economic benefits to certain in-state industries remains the favored pastime of state and local governments.17 While this case does not directly challenge the ability of states [1222]*1222to provide business-specific economic incentives, adopting a rule against the legitimacy of intrastate economic protectionism and applying it in a principled manner would have wide-ranging consequences. See Vieth v. Jubelirer, — U.S. —, 124 S.Ct. 1769, 1776-77, 158 L.Ed.2d 546 (2004) (“[J]udicial action must be governed by standard, by rule. Laws promulgated by [legislatures] can be inconsistent, illogical, and ad hoc; law pronounced by the courts must be principled, rational, and based upon reasoned distinctions.”). Thus, besides the threat to all licensed professions such as doctors, teachers, accountants, plumbers, electricians, and lawyers, see, e.g., Oklahoma Statutes, title 59 (listing over fifty licensed professions), every piece of legislation in six states aiming to protect or favor one industry or business over another in the hopes of luring jobs to that state would be in danger. While the creation of such a libertarian paradise may be a worthy goal, Plaintiffs must turn to the Oklahoma electorate for its institution, not us.
E. Oklahoma’s Regulatory Scheme
Because we find that intra-state economic protectionism, absent a violation of a specific federal statutory or constitutional provision, is a legitimate state interest, we have little difficulty determining that the FSLA satisfies rational-basis review. As discussed above, see supra note 11, the Board enforces the FSLA in such a manner as to avoid any conflict with the “dormant” Commerce Clause. Moreover, we find no other federal statutory or constitutional provision that the FSLA violates. In particular, we note that, despite the FTC’s protestations before the trial court that the FSLA does not “advanc[e] the ends of the FTC’s Funeral Rule,” 18 the FSLA does not transgress any of the Rule’s express provisions. See 16 C.F.R. §§ 431.1-453.9. Hence, the FSLA need only be rationally related to the legitimate [1223]*1223state interest of intrastate industry protection. There can be no serious dispute that the FSLA is “very well tailored” to protecting the intrastate funeral-home industry. Craigmiles, 312 F.3d at 228. As such, “our inquiry is at an end.” United States R.R. Retirement Bd. v. Fritz, 449 U.S. 166, 179, 101 S.Ct. 453, 66 L.Ed.2d 368 (1980).
F. Craigmiles v. Giles
In so holding, we part company with the Sixth Circuit’s Craigmiles decision, which struck a nearly identical Tennessee statute as violating the Equal Protection Clause and substantive due process. Our disagreement can be reduced to three points.19 First, as noted by the District Court, Craigmiles’s analysis focused heavily on the court’s perception of the actual motives of the Tennessee legislature. Craigmiles, 312 F.3d at 227 (“The state could argue that the Act as a whole ... actually provides some legitimate protection for consumers from casket retailers. The history of the legislation, however, reveals a different story.... ”). The Supreme Court has foreclosed such an inquiry. Beach Communications, 508 U.S. at 315, 113 S.Ct. 2096 (“[Bjecause we never require a legislature to articulate its reasons for enacting a statute, it is entirely irrelevant for constitutional purposes whether the conceived reason for the challenged distinction actually motivated the legislature.”). Second, the Craigmiles court held that “protecting a discrete interest group from economic competition is not a legitimate governmental purpose.” Craigmiles, 312 F.3d at 224. As discussed above, we find this conclusion unsupportable. See Fitzgerald, 539 U.S. at 109-110, 123 S.Ct. 2156 (holding, after the decision in Craigmiles, that the objective of favoring one intrastate industry over another provides a rational basis to support legislation). Third, in focusing on the actual motivation of the state legislature and the state’s proffered justifications for the law, the Craigmiles court relied heavily on Cleburne v. Cleburne Living Center, Inc., 473 U.S. 432, 105 S.Ct. 3249, 87 L.Ed.2d 313 (1985). We find this emphasis misplaced.
A few additional words are in order regarding our last point of disagreement. In essence, Plaintiffs in this case “ask this court to engage in what they assert to be an exacting rational-basis standard set forth by the Supreme Court in Cleburne [.]” Jacobs, Visconsi & Jacobs, Co. v. City of Lawrence, 927 F.2d 1111, 1119 n. 6 (10th Cir.1991). Pursuant to their reading of Cleburne,20 “a court would be shrinking from its most basic duty if it abstained from both an analysis of the legislation’s articulated objective and the method that the legislature employed to achieve that objective.” Brown v. Barry, 710 F.Supp. 352, 355 (D.D.C.1989); see also Craigmiles, 312 F.3d at 227. This reading of Cleburne, however, constitutes a marked departure from “traditional” rational-basis review’s prohibition on looking at the legislature’s actual motives, see Beach Communications, 508 U.S. at 315, 113 S.Ct. 2096, and our obligation to forward every conceivable legitimate state interest on behalf of the challenged statute, see, e.g., Starlight Sugar, 253 F.3d at 146.
Despite the hue and cry from all sides,21 no majority of the Court has stated that [1224]*1224the rational-basis review found in Cleburne and Romer v. Evans, 517 U.S. 620, 116 S.Ct. 1620, 134 L.Ed.2d 855 (1996), differs from the traditional variety applied above. But see Lawrence v. Texas, 539 U.S. 558, 580, 123 S.Ct. 2472, 2485, 156 L.Ed.2d 508 (2003) (O’Connor, J., concurring in part) (“When a law exhibits such a desire to harm a politically unpopular group, we have applied a more searching form of rational basis review to strike down such laws under the Equal Protection Clause.”). Perhaps, as Justice O’Connor suggests, Cleburne and Romer represent the embryonic stages of a new category of equal protection review. See Cleburne, 473 U.S. at 458, 105 S.Ct. 3249 (Marshall, J., concurring in part and dissenting in part) (labeling Cleburne’s rational-basis review “ ‘second-order’ rational-basis review”). But “[e]ven if we were to read Cleburne to require that laws discriminating against historically unpopular groups meet an exacting rational-basis standard,” which we do not, “we do not believe the class in which [Plaintiffs] assert they are a member merits such scrutiny.” Jacobs, Visconsi & Jacobs, Co., 927 F.2d at 1119 n. 6.
On the other hand, Romer and Cleburne may not signal the birth of a new category of equal protection review. Perhaps, after considering all other conceivable purposes, the Romer and Cleburne Courts found that “a bare ... desire to harm a politically unpopular group,” Department of Agriculture v. Moreno, 413 U.S. 528, 534, 93 S.Ct. 2821, 37 L.Ed.2d 782 (1973), constituted the only conceivable state interest in those cases, see Clajon Production Corp. v. Petera, 70 F.3d 1566, 1581 n. 24 (10th Cir.1995) (forwarding this interpretation of Cleburne). Under this reading, Cleburne would also not apply here because we have conceived of a legitimate state interest other than a “bare desire to harm” non-licensed, time-of-need, retail, casket salespersons.
Finally, perhaps Cleburne and Romer are merely exceptions to traditional rational basis review fashioned by the Court to correct perceived inequities unique to those cases. If so, the Court has “fail[ed] to articulate [when this exception applies, thus] provid[ing] no principled foundation for determining when more searching inquiry is to be invoked.” Cleburne, 473 U.S. at 460, 105 S.Ct. 3249 (Marshall, J., concurring in part and dissenting in part). Regardless, the Court itself has never applied Cleburne-style rational-basis review to economic issues. See, e.g., Fitzgerald, 123 S.Ct. at 2159-60; Beach Communications, 508 U.S. at 315, 113 S.Ct. 2096; Nordlinger, 505 U.S. at 11-13, 112 S.Ct. 2326. Following the Court’s lead, neither will we. Thus, we need not decide how Cleburne alters, if at all, traditional rational-basis review because, even under a mod[1225]*1225ified rational basis test, the outcome here would be unchanged.
V. CONCLUSION
We do not doubt that the FSLA “may exact a needless, wasteful requirement in many cases. But it is for the legislature, not the courts, to balance the advantages and disadvantages of the [FSLA’s] requirement[s].” Williamson, 348 U.S. at 487, 75 S.Ct. 461. Under our system of government, Plaintiffs “ ‘must resort to the polls, not to the courts’ ” for protection against the FSLA’s perceived abuses. Id. at 488, 75 S.Ct. 461 (quoting Munn v. Illinois, 94 U.S. 113, 134, 24 L.Ed. 77 (1876)).
As Winston Churchill eloquently stated: “[Djemocracy is the worst form of government except for all those other forms that have been tried.” Winston Churchill, Speech at the House of Commons (Nov. 11, 1947). Perhaps the facts here prove this maxim. A bill to amend the FSLA to favor persons in the Plaintiffs’ situation has been introduced in the Oklahoma House three times, only to languish in committee. See H.R. 1460 (Okla.2003); H.R. 1057 (Okla.2001); H.R. 1083 (Okla. 1999). While these failures may lead Plaintiffs to believe that the legislature is ignoring their voices of reason, the Constitution simply does not guarantee political success.
Because we hold that intrastate economic protectionism, absent a violation of a specific federal statutory or constitutional provision, is a legitimate state interest and that the FSLA is rationally related to this legitimate end, we AFFIRM.
