Chairman-Mao said: No, because its cheaper to just pay workers than it is to pay people to keep the slaves in check (make sure they don't try to revolt). |
What if it weren't then? What if in the future there were this cheap technology/pill that controls/drugs a person into doing what you want, and you didn't need someone to keep them in check? Would you then embrace slavery?
More generally, is your position against slavery a purely economical one, or do you also think it's ethically wrong?
