In my view, a German soldier fighting for Nazi Germany is pretty bad, putting on the title of SS while swearing an oath to Hitler and willing to die for him and the Nazi ideals is VERY fucking bad.
Difference is was that we were in a the middle of a global war.
I’m not an economist so I don’t know how to make the economy and money just “work” but I would say that a wartime economy is different from a peacetime economy.
Because most people will still continue to buy things.
