Although Americans like to believe that they live in a classless society, Stanley Aronowitz demonstrates that class remains a potent force. Defining class as the power of social groups to make a difference, he explains that social groups such as labor movements, environmental activists, and feminists become classes when they make demands that change the course of history. "WithHow Class WorksAronowitzputs the subject of social class squarely on the intellectual agendathough in a new, inclusive, and dynamic form. Like his influentialFalse Promises, How Class Worksis both intellectually exciting and morally challenging."Barbara Ehrenreich "InHow Class WorksAronowitz argues for the enduring vitality of the concept of social class as a way of understanding social relations. This is a significant contribution to social theory, an argument certain to be widely considered, debated, and tested."George Lipsitz, author ofAmerican Studies in a Moment of Danger "An intellectually captivating book on a topic that remains as timely and significant as ever."Howard Kimeldorf, University of Michigan
