The episode explains what pulled millions of workers to new places: the industrial mobilization that began with Roosevelt's December 1940 promise of an arsenal of democracy. Federal money and cost-plus contracts produced about two-thirds of Allied weaponry, including some 2,700 Liberty ships, and unemployment fell from about 14 percent to 1.2 percent by 1944.
Production totals differ slightly by tally. Credit is shared among government direction, federal money, private industry and labor, and economists still debate the longer-run picture of the war's effect on the Depression.
