Its more than just money, its the amount of resources per person and the power over X amount of people that follow your rule. Literally until we set up a system like in star trek where EVERY ONE is free to do anything they wish to pursue (so long as it does not harm others) and EVERY ONE has access to all resources; The world is never truly going to get better so long as there is some one in charge with a stock pile of everything and every one has to obey them.
