I think many could find purpose with hobbies, charity, and children. The main issue I have is how does one pay for that and support themself? I would gladly quit my job if I had the means.
So long as there is work, the people who have a smaller share always have the opportunity of improving their lot by working harder and smarter than others.
A society with no work is basically one in which everyone lives off their assets, in which wealth primarily comes through inheritance. A society with even more inequality than today, but with far less social mobility.
I hope that isn't your worldview, it sounds lonely.
