Yeah, for that reason I really struggle to imagine an actually stable communist state. It's like balancing a top without spinning it, and even if you manage that, expecting that to be a permanent solution.

I wrap my head around that by thinking of communism as the limit of socialism. It doesn't/can't actually exist because greedy people will always exist to steal power from their neighbors, but a socialist society can approach it.
