The equilibrium in the distribution of powers between the Federal Government and the States as established by the Constitution has been seriously disturbed because the new powers that the authorities acquired for the most part accrued to the Union and not to the States. This is not the effect of sinister machinations on the part of mysterious Washington cliques, eager to curb the States and to establish centralization. It is the consequence of the fact of the fact that the United States is an economic unit with a uniform monetary and credit system with free mobility of commodities, capital, and men among the States. In such a country, government control of business must be centralized. It would be out of the question to leave it to the individual States. If each State were free to control business according to its own plans, the unity of the domestic market would disintegrate. 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.
