Sex is the first thing that comes to mind.
Like big brother, it would be far more about relations between people(more on the instinct of sex:) but it would be soo boring. The good point about work is it takes your mind of things. But no work, no money you would have to keep physically active: competition between people in sports would be massive! (A source of violence-gladiator style.) Familys again choosing mates.
But really i dont know, what people would do? You would be more with the raw essence of life.- intoxication in music, poetry, book's, spirtuality, people, myths, food and art(& mind altering drugs
) would all
be soo different: the hunter gatherer mode simply wouldnt be needed. Infact would it not just add to hate and resentment between people? Rules: would they even be needed? Morality?
Its great a thought to contemplate. Working the best part of your life now and to what end: money! Dont get me wrong today life is interesting,-- but better than the way people once lived (i dont think so!) Beggers cant be choosers.
