By most accounts some (not all) but some primitive people had quite pleasant, stress-free lives. The African pygmies, for instance, supposedly only hunted a few hours out of the week and otherwise lolled about, quite happily. But most Africans of that type were wiped out by the Bantu.
The problem, of course, is that the survival (and expansion) of the fittest kicks in. Eventually, the people willing to putter around in an open boat are bought out, undersold, or otherwise replaced by fishing companies. Then, land by the shore hits 500K per quarter acre as people with hardworking jobs push up the price.
