The wars are not economically comparable d. The economy in WWII was partially government controlled. Long term, this causes problems. However, when fighting a war on the scale of WWII it is necessary. Spending continued after the war because ordinary people had savings that they could not spend during the war. Also, military spending did not completely dry up due the growing Soviet threat. The other problem is that the federal debt before WWII was not the same relative size as it is now. There is quite a bit more to this if you have time to look into it.
