Question: how much money did the government spend in 1945?
Answer: The number of Americans required to pay federal taxes rose from 4 million in 1939 to 43 million in 1945. With such a large pool of taxpayers, the American government took in $45 billion in 1945, an enormous increase over the $8.7 billion collected in 1941 but still far short of the $83 billion spent on the war in 1945.
