also, failed attempts at socialism and the rare anarcho-communism ones were, to the best of my knowledge, before the age of abundance. without abundance, economic problems are indeed tougher and little different between different systems. but with abundance, communist arrangements can focus on maintaining it and distributing abundance fairly, whereas capitalism and feudalism have to deal with maintaining the inequality they rely on by force, and only insane and unjust reasons (like monkeys piling up enough bananas for a million lifetimes) to justify them. so maybe now (or after it crumbles further) could be a good time to give them another try, or at least one try for real? are you so scared of a possibility that it might work that you'd rather suppress it? would you rather bet on a known-failing, known-unsustainable, and known-self-destructive system instead?
