If there were still wages they would only be something extra as a reward, rather than something workers need to live.

Personal property, remember?

It's not unimaginable for there to be no wages at all, though. No one has to pay me to clean my house, cook my food, or grow my own garden. No one had to pay me to help clean up the trailer park when we were hit by a huge storm that knocked down a bunch of trees. Truly voluntary work for no reward other than good feelings and social esteem shouldn't be underestimated.

That's... probably not something that would be realistic for people like us who grew up under wage slavery, though. We probably do need rewards to do truly difficult work because we've been traumatized by our material conditions to associate working hard with suffering.
