Step-by-step explanation:
The war economy is characterized by an era of economic prosperity in the United States that brought the country out of the Great Depression. This happened because in wartime American factories produced more, which increased the economic power of the population. The United States produced and sold weapons and supplies to the Allies. It can be said that Pearl Harbor was an economic landmark in the war service, government entities and war councils mobilized themselves to manage the economic war production that grew substantially by the war efforts in the country.
With this economic boom, there were several job openings to be filled, which in fact contributed to the mass migration of people in the country.
