It broke the back of the Catholic church and feudalism. Peasants got their first pay raise... ever.

You're missing maybe the most important part of this: ...eventually. It was at least 40 years after the plague hit, and probably more like 70-100, depending how exactly you're counting. AKA it might get better after we're all dead

I think feudalism carried on for 200 more years

I think there's a comic series about that.
