1943. The public paid ¾ of the face value of a war bond and received the full face value back after a set number of years. This shifted their consumption from the war to postwar and allowed over 40% of GDP to go to military spending, with moderate inflation. Americans were challenged to put "at least 10% of every paycheck into Bonds". Compliance was very high, with entire factories of workers earning a special "Minuteman" flag to fly over their plant if all workers belonged to the "Ten Percent Club". There were seven major War Loan drives, all of which exceeded their goals. Labor The unemployment problems of the Great Depression largely ended with the mobilization for war. Out of a labor force of 54 million, unemployment fell by half from 7.7 million in spring 1940 (when the first accurate statistics were compiled) to 3.4 million by fall of 1941 and fell by half again to 1.5 million by fall of 1942, hitting an all-time low of 700,000 in fall 1944. There was a growing labor shortage in war centers, with sound trucks going street by street begging for people to apply for war jobs. Greater wartime production created millions of new jobs, while the draft reduced the number of young men available for civilian jobs. So great was the demand for labor that millions of retired people, housewives, and students entered the labor force, lured by patriotism and wages. The shortage of grocery clerks caused retailers to convert from service at the counter to self-service. With new shorter women clerks replacing taller men, some stores lowered shelves to .

Women Women also joined the workforce to replace men who had joined the forces, though in fewer numbers. Roosevelt stated that the efforts of civilians at home to support the war through personal sacrifice was as critical to winning the war as the efforts of the soldiers themselves. "Rosie the Riveter" became the symbol of women laboring in manufacturing. Women worked in defense plants and volunteered for war-related organizations. Women even learned to fix cars and became "conductorettes" for the train. The war effort brought about significant changes
