Human greed is the common point of failure in any of societal systems. In any system … capitalism, socialism, religious, commune, authoritarian … the common thing that holds it together is concentration of power. The problem that it suffers from is … concentration of power.

No matter what group you create, power eventually gets concentrated to smaller groups of people and it only attracts a certain group of individuals who only understand the need to want power and control over everyone and everything to the detriment of everything else.

Once we find a way to build a societal system that is able to distribute power and keep any one or group of people from dominating everyone else, then we might have a chance of developing a sustainable civilization. In the meantime, no matter what you want to call it or do with it, if the end process just concentrates power to a small group of fallible ignorant humans, nothing will ever work.
