I think there’s a correlation between wealth and facism to some degree. But IMHO not because a company already existed back in that era.
That's also not what I said. I said almost all of those families were active members of the Nazi party. In fact, some of the billionaires that control or did control massive and popular German corporations not only benefited from forced labor sourced from Nazi concentration camps, but were members of the SS themselves.
So no, while being rich doesn't make you a fascist in and of itself, being a multi-generational Nazi family, that profited from the Third Reich, used Jewish slaves, actively took part in the "final solution to the Jewish problem", and has taken steps to hide that past, does make you a fascist. Some of the German billionaires that are alive and running these corporations today have nothing but praise for their fathers who were alive and active Nazis during WW2.
You think all the people with 401(k)s voted for Trump? I'm curious as to what leads you to that conclusion?
