Apparently the Court believes that when "an unelected federal judiciary" makes decisions as to whether a particular function is one for the Federal or State Governments, the States no longer may engage in "social and economic experiment." § 152(2); the Labor-Management Reporting and Disclosure Act, 29 U.S.C. We held that the inquiry into a particular function's "traditional" nature was merely a means of determining whether the federal statute at issue unduly handicaps "basic state prerogatives," id., at 686-687, 102 S.Ct., at 1354-1355, but we did not offer an explanation of what makes one state function a "basic prerogative" and another function not basic. At one time in our history, the view that the structure of the Federal Government sufficed to protect the States might have had a somewhat more practical, although not a more logical, basis. Nonetheless, it long has been settled that Congress' authority under the Commerce Clause extends to intrastate economic activities that affect interstate commerce. Incidental to this expansion of the commerce power, Congress has been given an ability it lacked prior to the emergence of an integrated national economy.

The point of the inquiry, however, has remained to single out particular features of a State's internal governance that are deemed to be intrinsic parts of state sovereignty.

326 (1946) (dissenting opinion). But see United States v. Scott, 437 U.S. 82, 86-87, 98 S.Ct. This Court has been increasingly generous in its interpretation of the commerce power of Congress, primarily to assure that the National Government would be able to deal with national economic problems. If the power was not given, Congress could not exercise it; if given, they might exercise it, although it should interfere with the laws, or even the Constitution of the States."

This rephrasing is not a distinction without a difference; rather, it reflects the Court's unprecedented view that Congress is free under the Commerce Clause to assume a State's traditional sovereign power, and to do so without judicial review of its action. The application of the FLSA to SAMTA would be constitutional even had Congress not provided federal funding under UMTA. 392 U.S. at 205, 88 S.Ct., at 2028. 455 U.S., at 686, 102 S.Ct., at 1354.

It extends to those activities intrastate which so affect interstate commerce, or the exertion of the power of Congress over it, as to make regulation of them appropriate means to the attainment of a legitimate end, the effective execution of the granted power to regulate interstate commerce. 772 (1893), a defense quoted with approval in Erie R. Co. v. Tompkins, 304 U.S. 64, 78-79, 58 S.Ct. In an era when interstate commerce represented a tiny fraction of economic activity and most goods and services were produced and consumed close to home, the interstate commerce power left a broad range of activities beyond the reach of Congress. 543 (1954); La Pierre, The Political Safeguards of Federalism Redux: Intergovernmental Immunity and the States as Agents of the Nation, 60 Wash.U.L.Q. As a result, there is now a real risk that Congress will gradually erase the diffusion of power between State and Nation on which the Framers based their faith in the efficiency and vitality of our Republic. 1792, 1801, 44 L.Ed.2d 363 (1975) (dissenting opinion), and, despite the difficulties that this Court and other courts have encountered so far, it normally might be fair to venture the assumption that case-by-case development would lead to a workable standard for determining whether a particular governmental function should be immune from federal regulation under the Commerce Clause. Congress' treatment of public mass transit reinforces our conviction that the national political process systematically protects States from the risk of having their functions in that area handicapped by Commerce Clause regulation.21.

Of course, the Commerce Clause by its specific language does not provide any special limitation on Congress' actions with respect to the States.
