To quote Justice William Rehnquist: “one of the greatest 'fictions' of our federal system is that the Congress exercises only those powers delegated to it, while the remainder are reserved to the States or to the people. The manner in which this Court has construed the Commerce Clause amply illustrates the extent of this fiction. Although it is clear that the people, through the States, delegated authority to Congress to 'regulate Commerce ... among the several States' (Commerce Clause), one could easily get the sense from this Court's opinions that the federal system exists only at the sufferance of Congress."
