It's not so much that, it's that feudal life is hard work and oppressive in a different way. Capitalism relieved thos issues while adding many of its own.

Anyone who's got an idea of what farmwork takes knows when you do need to work it's backbreaking and you do it or you starve. The work is less consistent but still pretty hard and in hard times survival can be a lot more difficult than urban work or artisanship.

Remember, the landowners Mao killed were mostly Feudal, not capitalist.
