It doesn't matter, you don't even know the cost of the Marshall plan based on your answer.
And YES, that is exactly what workers and companies DID DO in the aftermath, they LITERALLY - - QUITE LITERALLY, DID in fact,
"crawl out of the rumble and went back to making radios, cards, medicinals, and cameras".
The Marshall Plan cost the United States $12 billion, which is nearly $100 billion in 2018 US dollars.
A hundred billion given to Europe today would be a nice gift but hardly capable of rebuilding much more than maybe a single medium sized manufacturing corporation.
The FACTS:
Agricultural production was 83% of 1938 levels, industrial production was 88%, and exports 59%.
Exceptions were the United Kingdom, the Netherlands and France, where by the end of 1947 production had already been restored to pre-war levels before the Marshall Plan. Italy and Belgium would follow by the end of 1948.
Germany began small steps toward restoration of its industrial capacity as early as 1947 but it wasn't maybe till 1949 or 1950 that Germany's industrial output was fully restored.
Stop moving the goalposts. Your post argued that the reason our economy was so sound was because we were the "only man standing" after WW2, until as you put it, almost the 1960's.
Our aid to Japan was miniscule by comparison to what we GAVE AWAY to them in the 1970's.
Russia did not receive a DIME from us for WW2 under the Marshall Plan.
THEY REJECTED our OFFER.
Stop pulling things out of your butt and calling them ice cream. This is why no one respects your debates.
Much of the postwar economic boom was PENT UP consumer demand after years of wartime rationing, and returning servicemen eager to go back to work and start families.
Give up, you live in an alternate world with alternate history, made of alternate facts.
