I’ve been looking for a while about this and I still haven’t found a clear answer. On one hand I’ve heard that Nazi Germany was powerful, brang Germany out of the Depression, and almost conquered Europe. On the other I’ve heard it was actually horribly inefficient due to Hitler’s incompetence and extreme competition within the branches of government. Which is true, if any?
Not to deter further answers, but you'll definitely want to check out this answer by u/ruhr1920hist, detailing Nazi Efficiency as by-and-large a myth.
