The government started getting bigger and more intrusive almost from the moment it was birthed. From Thomas DiLorenzo at lewrockwell.com:
All governmental power is propped up by an avalanche of myths and superstitions about the alleged benevolence, omniscience, honesty, selflessness, and magnanimity of the state, coupled with critiques if not outright demonization of private property, free market voluntarism, private enterprise, limited government, the rule of law, the free society, and all those who educate about and advance such concepts. Your author once co-authored a book entitled Official Lies: How Washington Misleads Us, about mountains of such myths and superstitions. A case can be made that at the top of the list of statist myths and superstitions is the myth of American nationalism — about the supposed “superiority” of a virtually unlimited, centralized and consolidated government, coupled with the never-ending hatred and demonization of federalism, states’ rights, nullification and secession, and anything else that challenges the notion of the “supremacy” of the central government.
