In a provocative new interpretation of a transforming era in American history, Maury Klein examines the forces that turned the United States from a rural agricultural society to an urban industrial one. Integrating social, economic, and business history, he stresses the driving role of technology and the emergence of a complex society of many cultures, lacking a cohesive center. The rise of a corporate economy, described by Mr. Klein, resulted in productive miracles unequaled elsewhere—but at the cost of great social dislocation in American life. Gradually there arose a society that organized and formalized traditional American values in new and unexpected ways. This transformation produced a surprising new center for the diverse and fragmented American social order: the consumer economy. The new order flowered after the turn of the century and was advanced by the consequences of World War I, which left the United States as the world's major power. The Flowering of the Third America is a vivid and authoritative portrait of the making of modern America.
