"In exchange for making me rich, I grant you the privilege of having enough money to pay your bills and maybe go to disneyland once in a while."
That's not a return on your effort for your own benefit; it's quite literally serfdom with extra steps. "You harvest me 1,000 acres and I'll let you keep two acres to take care of your family."
If you're not being paid adequately you're free to go work for someone else. I don't get why people act as if they're slave labor. If you don't like working for someone else then start your own company.
