Just to underscore how lowly and vicious the propaganda bigotry against Jews was/is; bankers weren't even a substantial percentage of the Jewish population. The other "allowed" higher income occupation, being a jeweler, was also viewed as cause for resentment (note that the English word for gemstone trinkets was conventionally based on the word "Jew"), as were Jewish merchants and shop owners. Most Jews, though, were working class artisans and laborers, like tailors, bakers, cobblers, brick masons, trash carters and street sweepers, again because of being legally barred from many job classes.
