A Comparison

From Defeating Nazis, Stopping Holocaust, Cost Less Than Wall Street Bailout by Ken Silverstein:

The cost to the United States of helping defeat Adolf Hitler, liberate Europe from fascist rule and halt the holocaust came to roughly $3.6 trillion, adjusted for inflation. The cost of the bailout, to date, comes to about $4.6 trillion. World War II was a steal — and with the $1 trillion difference there’s still enough left over to cover the past costs of the Marshall Plan and the The New Deal.
