Adapted in part from the Opportunity in America series of policy briefs, this volume focuses on social and economic mobility in the United States. The authors find that class or family background has a strong effect on individual success. They examine the possible reasons for this relationship, how it has changed over the past century, and the role of the economy, the welfare system, and education in opening up opportunities for the less fortunate.
