Were the Nazis really socialists? The proof – and numbers – are hard to find

I faced a problem.

I had found another one of those “universally known economic assumptions” that everybody assumes is true, but did not know for a fact whether or not it was. We all know these economic assumptions, and even we are guilty of assuming they’re true every day:

– Capitalism is the best economic system there is. (Proven true.)
– “The rich don’t pay their fair share.” (Proven false.)
– “Sexism is causing the wage gap.” (Proven false.)
– “Housing always goes up.” (Absolutely proven false.)
However, this one was going to be a little bit harder to prove:

Were the Nazis (the National SOCIALISTS) indeed socialist?
