One of the ideas that seems to be missed from the study of history and economy, was the effect on the total destruction of the Japanese and German industrial base - during WWII. Britain and USA, were left with their archaic industrial systems. After WWII, the Japanese and the German steel industry had to be completely reborn. (At the cost of primarily USA financing.) Those two countries had no more relics of the past…
You forgot that US took every German and Japanese engineer as prisoner. As a friend said, US chemical industry worked 40 years after the WWII with German patents.
