[V]oluntary exchange among individuals held morally responsible under the rule of law creates both prosperity and an unparalleled diversity of human choices. Such a model also has been a precondition of individuation and freedom. By contrast, regimes of central planning create poverty and occasion ineluctable developments toward totalitarianism and the worst abuses of power. Dynamic free-market societies, grounded in rights-based individualism, have altered the entire human conception of liberty and of dignity for formerly marginalized groups. The entire "socialist experiment," by contrast, ended in stasis; ethnic hatreds; the absence of even the minimal preconditions of economic, social, and political renewal; and categorical contempt for both individuation and minority rights. Our children do not know this true comparison.
