" Those who doubt that “the private sector” of the economy could sustain the expense of a free enterprise defense system would do well to consider two facts. First, “the public sector” gets its money from the same source as does “the private sector”—the wealth produced by individuals. The difference is that “the public sector” takes this wealth by force (which is legal robbery)—but it does not thereby have access to a larger pool of resources. On the contrary, by draining the economy by taxation and hobbling it with restrictions, the government actually diminishes the total supply of available resources. Second, government, because of what it is, makes defense far more expensive than it ought to be. The gross inefficiency and waste common to a coercive monopoly, which gathers its revenues by force and fears no competition, skyrocket costs. Furthermore, the insatiable desire of politicians and bureaucrats to exercise power in every remote corner of the world multiplies expensive armies, whose main effect is to commit aggressions and provoke wars. The question is not whether “the private sector” can afford the cost of defending individuals but how much longer individuals can afford the fearsome and dangerous cost of coerced governmental “defense” (which is, in reality, defense of the government, for the government ... by the citizens).
