The Masses Are the Ruling Classes handles a neglected theme: social policy in the United States is determined by mass consent. Contemporary explanations of decision making in the United States typically attribute power over policy making to a variety of hidden forces and illegitimate elites, holding the masses innocent of their own problems. Yet the enormous openness of the society and nearly universal suffrage sustain democratic consent as more plausible than the alternatives (conspiracy, propaganda, usurpation, autonomous government, and imperfect pluralism). Despite the multitude of problems that the nation faces, its citizens are not oppressed. The core problem that blocks the maturation of American society is not democratic participation, but its content; popular preferences are romantic rather than pragmatic. None of these programs achieve their ends of poverty reduction or behavioral change. Rather, they persist as testimonials to America’s romantic preferences. Thus, if the American people are largely responsible for social policy, then they are also responsible for the problems that beset the nation, notably enormous economic and social inequality. If the masses rule policy choice, then the persistence of material and social deprivation that lies easily within the economic capacities of the nation to address suggests that the nation abides its inequalities and suffering. The commitment of American society to policy romanticism and its rejection of pragmatism blocks its social development.
