Lol, this hyperbole is laughable. Feudal lords were obliged to provide shit for peasants; if such peasants rebelled, 9 times out of 10 they would be massacred on the spot. The degree of arbitrary rule they expressed is something we just lost knowledge of, in the first world; but go ask Africans or South Asians from regions infested by warlords, to get a taste.
What about one day you send your daughters to school, but it's the day Mr Lord decides he needs some new sex slaves, and your daughters just disappear? What about Mr Lord needs some cannon fodder for some hopeless adventure, so he just raids your village, rapes a few women, chains you and your kids, and leads you to inevitable death? That's just Another Day in Feudalism for you.
