"The characteristic feature of present-day policies is the trend toward a substitution of government control for free enterprise. Powerful political parties and pressure groups are fervently asking for public control of all economic activities, for thorough government planning, and for the nationalization of business. They aim at full government control of education and at the socialization of the medical profession. There is no sphere of human activity that they would not be prepared to subordinate to regimentation by the authorities. In their eyes, state control is the panacea for all ills...America is faced with a phenomenon that the framers of the Constitution did not foresee and could not foresee: the voluntary abandonment of congressional rights. Congress has in many instances surrendered the function of legislation to government agencies and commissions, and it has relaxed its budgetary control through the allocation of large appropriations for expenditures, which the Administration has to determine in detail."
