Why did the United States spend more than any other country during world war ll ?

The federal government spent about $350 billion during World War II — or twice as much as it had spent in total for the entire history of the U.S. government up to that point. About 40 percent of that came from taxes; the rest came through government borrowing, much of that through the sale of bonds.

All that money had to go someplace. A lot of it went to the West, especially California, where 10 percent of all the federal war spending took place. But the American economy rose just about everywhere else too. The civilian workforce grew 20 percent. The Gross National Product (the total of goods and services produced) more than doubled between 1939 and 1945. Wages and corporate profits went up, as did prices.
