Incidentally, we tolerate this kind of "slavery" just fine when we charge people rent for basic shelter. The cost of maintaining the asset (the house) is far less than the cost we actually charge people, so in your sense when I pay rent I am being enslaved by the landlord to support their lifestyle.
Finally, you brought up slavery. The guy I'm replying to just said "work is good". I don't think it's good that we make people destroy their bodies in amazon fulfilment centers. People know what's good for them, if they want to do work let them do the work they want. But to say "no, you have to do the work I want you to do" under the hypothesis that we have plenty of stuff to go around (and we absolutely do) is just sick.
