I don’t think that being a peasant was bad, it doesn’t seem to have been exploitative in the same way capitalism is. Peasants were largely farmers who grew food and provided the landowner with a percentage of their crop. They were integral to human survival and as far as I know the percentage taken by landowners was not comparable to the wealth extracted from workers today. Also they were essentially tasked with being in control of an area of land where they lived and worked.
