That myth ranks right up there with "FDR got us out of the Depression." Hitler put everyone to work (much like FDR), but he consumed every pfennig of capital in the country to do it.
His policies ate the guts out of the Germans' wealth to keep his war machine going. That was not economic growth, it was pure Keynesianism (who rather admired Hitler) on steroids.
True that. Germany was broke and needed other sources of wealth, which they obtained through the “donations” from their Euro neighbors. The Nazis were collecting loot any way they could, including stockpiling the gold teeth of their victims.
In fact, that’s why Hitler had to go to war when he did, Germany was on the verge of bankruptcy, war couldn’t wait.
