Who bought all that debt?
Asia was poor and both Europe and Asia were at war. They couldn’t buy it. I think the Federal Reserve was much more conservative back then (certainly not like now!). Was it all funded through Americans’ savings?
“Who bought all that debt?”
American citizens.
Less than 1% of the national debt was owned by foreigners in both 1933 and 1945.
Much of it in War Bonds, i.e. you’re right ... Americans’ savings.
