For starters the economy was trashed by Versailles. Then it was trashed by reserve Bank funding sozi policies aka the great depression. Then it was trashed by Hitler. Forget the bs. Hitler hired millions of men and paid then subsistence wages. The individual wealth was way less than usa. Also note that non nazi led the economy recovery. Look up Hjalmar Schacht By 1939 German was largely bankrupt. It needed to loot other nations treasuries which it did. Finally understand that greater Reich economy was much larger than ussr in every stat except oil production yet ussr out produced them. Because their economic system was inefficient. It was so bad udet killed himself trying to fix it though he did a number of good things Speer took credit for. One funny story was that nazis sent the same amount of aluminum to all their factories. Easy accounting I guess. Fighter factories got too much. Bombers too little. That's central planning for you
