This chapter sets the conceptual and historical context of the argument and describes patterns of U.S. public opinion that the book seeks to explain. It situates the book’s argument within scholarship on the politics of economic inequality, public opinion, news framing of policy debates, and the political economy of the media. The chapter also develops a new theory of media dynamics. This theory explains how corporate and governmental influences shaped by media policies filter news coverage of economic and social welfare policy issues. The chapter also summarizes the book’s contribution to empirical research on material power in American politics and to scholarship about the tensions between neoliberalism and democracy.
