Although it sounds like a mere historical curiosity, it’s a reconfirmation that collective policies are shaped more by the material conditions than by ‘ideology’. (Of course, it’s also useful for diminishing the uniqueness of both neoliberalism and Fascism, if ‘owning the libs’ is your thing.)
I’ll keep your suggestion in mind and bookmark the link you gave me. As for this, I’ll give it a shot and read through it. I also read a Soviet documentary on Krupp and the general finances of the Nazi party and their allies around the WWII years and before that as well.
