Hello everybody, I hope you're having a great day!
I've been reading Mein Kampf and Hitler makes it clear of his hatred of Marxism. Why then, did he join the Nationalist Socialist German Worker's Party? Weren't their other anti-semitic nationalist parties that wanted Austria to join Germany again? I've read the Communist Manifesto and Das Kapital, and Hitler doesn't really seem like a socialist. I know a lot more about Hitler and the Nazi's social policies than I do about their economic policies, so this confuses me.
Thank you in advance.
The 'Socialist' is doing a lot of work, when it should be read as a phrase, 'National Socialist'. More can always be said if anyone would like to put their oar in; for the meantime, our FAQ includes a section on 'How Socialist was National Socialism?'
(Spoiler alert: The answer is "Not very".)
The NDAP took great efforts to distinguish itself from what everyone else referred to as "socialism", and practiced pragmatism more than anything else, when it came to economic reform. Here's a great answer from /u/Fjosnisse on the NDAP's policy platform at the time Hitler first became interested in it. It boils down to: all people who are ethnically German should have access to jobs and a good standard of living at all costs. Nationalizing industries to give governmental control over hiring is a very acceptable step to that goal. Any and all deemed "injurious to the State" should be executed.
In practice, however, this question is heavily addressed in FAQs. Here's the section on Nazi economic policy in general, and here's a specific answer to the question of how left-wing Nazi Germany actually was. Their key goal was eliminating the trade deficit, and they exercised enormous central control over such things.
But the main take away to your question should be that the primary ideological movement wasn't economic, but nationalist. Anything which would allow control over who was trading and profiting was considered fair game.
