What were two long term effect of the Black Death on European society?

One long term effect was the population decrease. Once populated villages and towns were left to rubble and ruins after the black death hit. Large, working expanses of land were left to deserted wilderness, crops were left to rot in the ground, and cattle were left to roam around until they perished. Another one was a line of brutal attacks towards the Jewish. Any body with a skin disease like acne or psoraiasis was thought to be a lepur, and leprosy was thought to be an outward proof of a disturbed soul. They were wiped out through Europe. This was very common in Switzerland; they were known to burn them in their houses at hundreds at a time. They even attacked when and where there was no plague, saying that they were the king's permission, giving them a reason to wipe them out pointlessly.
