Interestingly, despite the movement of times, in some industries those of Jewish descent still have a financial stranglehold which those not of the in-group have to beg for membership or break the law to match the advantage the businesses at the core have created.

As I understand it, success in business, pointed at because they were identifiably different in some typical racist ways (gosh, what a big hooked nose, they must be evil!), created envy which was bred into hate. Ironic that the campaign for Aryan supremacy built it's approach on the fact that someone was better/more successful than them and had to be pulled down.
