Challenging the view that managerialism is a form of capitalism and that capitalism has eclipsed socialism, Pena shows that the managerial or new class is an exploiting class. The work of Thorstein Veblen, James Burnham, John Kenneth Galbraith, and Kevin Phillips, he suggests, forms a little-known century-long tradition of reflection on the managerial revolution as well as on the conflux of values and socioeconomic practices that Pena dubs economic barbarism. Building on the work of these thinkers, he argues that industrial barbarism and the managerial revolution led to the decline of U.S. capitalism and its replacement by managerialism, a form of nationalistic socialism in which educated white-collar personnel employed by the state and corporate bureaucracies have become a new exploiting class that receives the bulk of the national wealth. Thus managerialism replaced industrial barbarism with a new form of economic barbarism.

This managerial barbarism has fostered an unequal distribution of wealth that has penalized the middle and lower classes with stagnant or declining incomes, growing job insecurity, unemployment, and underemployment. Unless managerialism can find a way out of persistent poverty and declining living-wage job opportunities, these problems are likely to continue afflicting a sizable portion of the population. If managers put an end to economic barbarism, they have a chance to create a society characterized by generalized prosperity, leisure, and opportunity. It is more likely, however, that economic barbarism will continue to be an integral part of managerialism and, consequently, managerialism will face a sudden social upheaval or a gradual decline.
