The Crisis of the Old Order by Arthur M. Schlesinger Jr.
Portraying the United States from the Great War to the Great Depression, covers the Jazz Age and the rise and fall of the cult of business. For a season, prosperity seemed permanent, but the illusion came to an end when Wall Street crashed in October 1929. Public trust in the wisdom of business leadership crashed too. With a dramatist's eye for vivid detail and a scholar's respect for accuracy, Schlesinger brings to life the era that gave rise to FDR and his New Deal and changed the public face of the United States forever.
