The real myth is that the Soviets just threw meat waves and would have lost without Uncle Sam. Most of that was anti communist propaganda and any serious (ie non-narrative driven) historian knows the truth about the industrial and military achievements of the Soviets in that war.

“In all, $31.4 billion went to the United Kingdom, $11.3 billion to the Soviet Union, $3.2 billion to France, $1.6 billion to China, and the remaining $2.6 billion to other Allies.” ~12x that when counting for inflation.
