I disagree with that. I know a handful of persons who are 'unemployed' in the sense that they don't work for money, and don't have money at all (most of them I met in a natural squat, NDDL, and some are still living the life at 40-50 in what is called 'ecolieux' in my country). They're still the happiest persons I know, even the two sober ones (no weed nor alcohol, for hippies, feel weird, but they have more time for music. And sex I guess).

They still work for the ecolieux: prepare food, care for vegetables, fruits and poultry, odd jobs, but they aren't paid for it.
