"State control of business would be practicable only if every State were in a position to separate its territory from the rest of the nation by trade and migration barriers and an autonomous monetary and credit policy. As nobody seriously suggests breaking up the economic unity of the nation, it has been necessary to entrust the control of business to the Union. It is in the nature of a system of government control of business to aim at the utmost centralization. The autonomy of the States as guaranteed by the Constitution is realizable only under a system of free enterprise. In voting for government control of business the voters implicitly, although unwittingly, are voting for more centralization." - Mises, Bureaucracy.
