Book excerpt: Argues that ordinary people exercise extraordinary political courage and power in American politics when, frustrated by politics as usual, they rise up in anger and hope, and defy the authorities and the status quo rules that ordinarily govern their daily lives. By doing so, they disrupt the workings of important institutions and become a force in American politics. Drawing on critical episodes in U.S. history, Piven shows that it is in fact precisely at those seismic moments when people act outside of political norms that they become empowered to their full democratic potential.
