This reference work provides an authoritative and comprehensive resource for both students and scholars who are interested in learning more about the rich-poor divide in the United States—a divide regarded by many lawmakers, researchers, pundits, and concerned citizens as one of the nation's most serious problems. The book provides important historical background for understanding how the nation has grappled with (or ignored) this issue in the past, examines specific causes of inequality identified by observers across the political spectrum, and summarizes the potential consequences (both present and future) of economic inequality. This book examines more than 25 issues frequently cited as factors contributing to the rapidly widening gap between socioeconomic classes in the U.S., ranging from such demographic factors as race and gender to tax code provisions and differences in access to quality education and health care. The book also provides both a retrospective and prospective look at government policies aimed at addressing inequality or assisting the poor. Finally, the book looks ahead to survey the future of inequality in America.
