You have no idea what serfs are.
>There is no commonly accepted modern definition of feudalism, at least among scholars
"As with slaves, serfs could be bought, sold, or traded (...), abused with no rights over their own bodies, could not leave the land they were bound to, and could marry only with their lord's permission."
Does anyone really think this is how Uber drivers live?
They have very little control over their lives and work, Uber does not let them set prices and they arent making enough money to go retire early. I refer to them as serfs in that they have to answer to Uber with no actual negotiating power on their own.
How is that "they have to answer to Uber"?
