Yes, Jewish people were famous and successful money lenders, circumstances and european antisemitism made it so. Jews were not permitted to own property. So the only place they could live were the cities (burgs => bourgeoisie). Christians were prohibited from lending money with interest. So, the Jews couldn't own land, couldn't farm or infringe upon protected guild businesses, but they could lend money, with no competition from the Christians.

I don't view money lending as evil. I wouldn't lend money without interest to people who I don't know. I don't think it was rational of the Church to label all money lending as usury and ban it. Christian merchants went to a lot of trouble to mask interest payments, but the Jews were free to do it in the open.

The Jews were successful, and so the people hated them. They were frequently targets of pogroms, expulsions and lynching both by jealous individuals and by the covetous state that wanted to confiscate their property.

People that actually believe anything hitler said are complete and utter morons. Losers who place blame for their own difficulties upon an entire "race" of people.
