How is paying me money any different if my only option if I quit was live on the streets and starve?
Monopoly on means of survival is effective slavery. People in early agricultural societies didn't exactly have many choices.
This is the argument behind the movements for a living wage. However this is now, no early agricultural society, just first world shining light capitalism. http://en.m.wikipedia.org/wiki/Living_wage
There are huge limits to capitalism in terms of automation. We are going to hit those limits in our lifetime and society is going to need some drastic adaptations.
