The idea that medieval peasants somehow had more free time than the average modern american still is absolute bullshit
Paleontologists will tell you otherwise. One reason you had all those giant cathedrals going up in the Medieval Era stemmed from the enormous excess labor just wasting around in between harvest seasons.
Agricultural surplus creates free time. It’s the whole reason why people opt for farming over hunter gathering.
This but unironically. I’ve got a coworker who took vacation days to help build a temple up in Pennsylvania. He was incredibly proud of his contribution and happy to participate.
