background
Many historians have characterized the period between the two world wars as the United States' traumatic "coming of age," despite the fact that U.S. direct involvement was relatively brief (1917-1918) and its casualties many fewer than those of its European allies and foes. John Dos Passos expressed America's postwar disillusionment in the novel Three Soldiers (1921), when he noted that civilization was a "vast edifice of sham, and the war, instead of its crumbling, was its fullest and most ultimate expression." Shocked and permanently changed, Americans returned to their homeland but could never regain their innocence.
Nor could soldiers from rural America easily return to their roots. After experiencing the world, many now yearned for a modern, urban life. New farm machines such as planters, harvesters, and binders had drastically reduced the demand for farm jobs; yet despite their increased productivity, farmers were poor. Crop prices, like urban workers' wages, depended on unrestrained market forces heavily influenced by business interests: Government subsidies for farmers and effective workers' unions had not yet become established. "The chief business of the American people is business," President Calvin Coolidge proclaimed in 1925, and most agreed.
