“Historically one of the main defects of constitutional government has been the failure to insure the fair value of political liberty. The necessary corrective steps have not been taken, indeed, they never seem to have been seriously entertained. Disparities in the distribution of property and wealth that far exceed what is compatible with political equality have generally been tolerated by the legal system. Public resources have not been devoted to maintaining the institutions required for the fair value of political liberty. Essentially the fault lies in the fact that the democratic political process is at best regulated rivalry; it does not even in theory have the desirable properties that price theory ascribes to truly competitive markets. Moreover, the effects of injustices in the political system are much more grave and long lasting than market imperfections. Political power rapidly accumulates and becomes unequal; and making use of the coercive apparatus of the state and its law, those who gain the advantage can often assure themselves of a favored position. Thus inequities in the economic and social system may soon undermine whatever political equality might have existed under fortunate historical conditions. Universal suffrage is an insufficient counterpoise; for when parties and elections are financed not by public funds but by private contributions, the political forum is so constrained by the wishes of the dominant interests that the basic measures needed to establish just constitutional rule are seldom properly presented. These questions, however, belong to political sociology. 116 I mention them here as a way of emphasizing that our discussion is part of the theory of justice and must not be mistaken for a theory of the political system. We are in the way of describing an ideal arrangement, comparison with which defines a standard for judging actual institutions, and indicates what must be maintained to justify departures from it.”
