Fun fact: the anti-Semitic stereotypes about Jews having lots of money/being greedy/cheap began in the Middle Ages thanks to Christian laws.
The Christian church began forbidding Christians from having professions that involved lending money, banking, or pawn work. It was because the church believed that money was ultimately unclean so although it was considered a necessity, Christians were instructed to deal with it as little as possible.
But someone still needed to run all of those money-based businesses. So these societies which were already run by Christian leadership basically made it a rule that these businesses had to be run by Jews since they were already “unclean”. Furthermore, due to other restrictions on Jewish people in these areas, these money-based positions were pretty much some of the only jobs Jews could legally hold.
This eventually led to numerous stereotypes involving Jews and money. And the acidity of these stereotypes grew when Christian people and leaders became resentful of the livelihood Jews were able to achieve for themselves with these jobs.
So to sum up: Christian society forces Jews to hold down money-centered jobs since, according to the church, Jews were already going to Hell. Then, once they made lives with these roles they were forced into, Jews were mocked and hated for being successful.
