Your post was a view point that we couldn't work less while maintaining modern conveniences and luxuries, at least that's how it's coming across.
If your point was simply that in pre-modern times they didn't have what we have today and that it was due to working too much for sustaining life to develop, then ok I guess. Maybe I misread the thread. The main post was about the fact we're working too many hours in our current society though so.. yeah.
