I don't doubt that people can be content with agrarianism, but worth remembering the inherent bias in recorded history towards the rich -- before the 19th century it seems very few people could read and write. Textual records are views of people who were relatively wealthy. I think that's true across cultures?

If you look at historical records of slavery, for example, you'll find "most people prospered", the people dying in cages weren't writing journals.
