In 1873, the mad dash for riches that followed the Civil War ended in a prolonged slump that ground on for six interminable years. On Black Thursday—September 18, 1873—the august banking house of Jay Cooke and Company failed because of problems in financing the Northern Pacific Railway. This event ignited a panic, leading to a stock-exchange shutdown, a string of bank failures, and widespread railroad bankruptcies. During the next few years, deflated by massive unemployment, daily wages plunged 25 percent, exposing many Americans to the horror of downward mobility.
