<human>:  What effects did World War II have on the United States?
<bot>: World War II had a significant impact on the United States. It created a strong economy through its mobilization of resources, dramatically increased the size of the U.S. military, and changed the most common concept of war. It changed the lives of many, not just in the United States, but throughout the world, as a result of its unprecedented destruction and loss of life. Physically, the war caused the destruction of infrastructure and infrastructure-related businesses, as well as an influx of refugees moving from country to country. Socially, the war caused greater awareness of civil and human rights, allowing for the creation of social systems such as the G.I Bill and civil rights legislation. Economically, the war saw an increase in public debt, investment in weapons technology, and a redistribution of resources. Institutionally, it changed the structure of the nation's government to one of a stronger form.
