Not exactly (from my reading). The Jewish communities tended to be fairly insular, and focused a lot of their business inward. They still dealt with outsiders, but money flow tended to move mostly in one direction, so it seemed like the Jewish people were much better off and “taking” from the rest, when the rest of the country struggled. It was really more that a marginalized community took care of their own. Shocking, right?

Plenty of other communities do the same. It’s still a bunch of scapegoating.
