In this discussion the author shows how the neoclassical paradigm leaves out the use of political means for monopolistic goals. This “interventionist” power of powerful economic actors is then systematically explained and its relations to economic power are explored. This leads the author to ask to what extent the American economy is competitive, once one takes into account the application of both economic and political power. The chapter closes with an analysis of the means suggested to enhance the encapsulation of the market, and to protect it from the political power of its own players, not just from that of the government.
