dont forget greed bob, thats the cause of all the problems today. a fair society does not and will never exist due to greed. it is within our nature. we used to club our rivals to death...now thats now allowed anymore so the club is now money and the more you have the bigger your club is.
in theory your idea works fine but in practice as has been shown time and time again we humans are incapable of a fair system for all.
