Humans organize in hierarchies and segregate according to class/caste because of the inherent reality of human nature and reality of inequality. There are certain aspects of sociopolitical organization that can be improved, but some other aspects of sociopolitical organization can not be changed. Someone will be in charge, and human political factionalism will continue, as long as men organize themselves into communities/societies. Unless "decentralization" denotes separated, fragmented, individual humans eeking out subsistence apart from other humans, centralized power structure alway remains. "Reform" is essentially discontented factions attempting to arrogate more power unto themselves at the expense of others. Nothing really changes in human sociopolitical drama.
