If you take all the collective wealth of the royal families, including the oil royals, the church, the greedy, soulless coorporate bigwigs, and the rest of the capitalist elite, and distibute it among the masses, you would find that the world would essentially be saved. (As long as some people don't become more equal than others, i suppose.)

Are you talking about a society (ala Star Trek) where there is "no poverty and no hunger, and the accumulation of wealth is not a driving force in society"?
