Absolutely. How can a society flourish when people are spending all their time for someone else? Full time work leaves little time for your health, family, friends, pets, and so on.
Actually, I neither work "for someone else" nor do I spend time with family, friends, etc for someone else either... not even for them. I do all of that for me. That my employers benefit, that family, friends, etc, benefit is besides the point from my perspective. It's not zero sum, after all.
Maybe the whole idea of working for someone is a strange one. Would people still work towards doing cool stuff if they were free to make/break associations on a project basis?
There might not be the cycle of hyperconsumption driven by superficial novelty we have now. But would it be replaced by something more or less interesting?
