Communism is pretty much anarchy. The only bad thing about communism, is the socialism before it.
Yes if we're trying to bring it into the modern world then yes that would be a problem but i'm saying if we as mankind started with Communism from day 1 (which it kinda did, Small villiages all work as one to get food provide shelter for everyone ect.) and stayed with it i think it would've turned out fine.
I say if you worked hard, you should keep your fucking money Castro took power and fucked them in the ass,
There is no money behind the true meaning of Communism ( a classless, moneyless, stateless Society)
like you said he got screwed because someone wanted to be in power, Society just can't handle where everyone is treated the same. Someone always believes they are entitled to more then others. in current society some may be entitled to more but with Communism everyone gets an equal share and everyone does their share of work.
