So I'm an American, not totally opposed to many of the socialist ideals such as free/subsidized healthcare and unemployment vouchers. I understand why people vouch for socialism and believe it to be the natural progression of a society that has become "post-scarcity". My question regards what the benefit/purpose of communism is.Socialism is about reducing disparity between the most wealthy and most impoverished through the regulations of a strong central government which makes sense logistically to me. My question is concerning how the allocations of resources functions in an innately stateless society. I've heard theories of everyone having equal joint ownership in all production in a communist society but assuredly there would have to be a group/committee to oversee the redistribution of resources no? Wouldn't such a group create a sort of power hierarchy as they now control the flow of resources? And such power could lead to corruption and an eventual oligarchy of those controlling the flow of resources. I want to understand the logistics of a legitimate communist society.The classical example of a communist society is a farming commune in which all produced on the land is shared according to the needs of the community. This works when applied to a small number of people coexisting on a farm in which everyone knows one another. This gets more complicated when manufacturing products such as computers which require hundreds of people to produce while the food is being produced by a separate population and now they must barter over the value of computers/food.This can be applied to any produced resource and so many factions of resource producers will develop independent groups that will advocate for their faction's best interests. Factions will undercut each other in order to remain competitive/viable and with no regulating body these factions will rise and fall and consume each other to the point of forming pseudo states within the communist nation. I don't understand how a true communist society prevents itself from quickly becoming an anarcho-capitalist paradise with no oversights/regulations if anyone knows?TL;DR: I want to know how a complex economic system exists under a communist society with no state to regulate businesses. I am looking to educate myself on how a true communist economy would work via /r/communism https://ift.tt/2OR4k4D
