How had the American economy been kicked into overdrive in 1944?

In 1944, the American economy was propelled into overdrive primarily due to the demands of World War II, which led to a massive increase in industrial production and employment. The war effort required vast quantities of supplies, resulting in factories operating at full capacity and the mobilization of millions of workers, including women and minorities. Government spending surged as the military contracted for weapons, vehicles, and other materials, driving innovation and economic growth. This wartime boom laid the groundwork for post-war prosperity in the United States.
