Maybe, just maybe it’s an alignment of ideology and geopolitical interests across the ruling class rather than genetics.
Maybe Jews were pushed into usury, maybe they’re over-represented in certain spaces like Ivy League schools because they’re wealthier on average, which buys a better education and more opportunities, perpetuating that wealth and success.
Pretty much anything the Nazis blame on Jewish genetics can easily be boiled down to class intetests without the weird blood libel conspiracism and insistence everyone they don’t like is a Jew.
