You are correct but

> It's mostly greed that prevents it

Greed is a human axiom. Anything that depends on humans not being greedy isn't worth the paper it's printed on. That's why capitalism won, despite its many faults: it requires human greed to function.

If that were the case why so much brainwashing is needed?

Because its the only way the people who would like to be in power and can't manage to produce anything anyone else wants can see to get themselves put in charge: convince enough other people that despite their freedom, high standard of living, etc. they are somehow oppressed.

Do you think perhaps the totalitarian dictatorships perverted the communist aims of the proles perhaps just a little bit?

No, I don't think so. From a historical point of view, everything is quite clear: after communists came to power, the most severe famines occurred even before this totalitarian dictatorship is build, as a consequence of these very tax policies, the purpose of which is "easily feed, clothe, house everyone".

Totalitarian dictatorship comes later, as the problem transform to "we can easily feed, clothe, house everyone, but they don't want to, so we should force them"

Pretty sure the Bolsheviks developed their bloodthirsty authoritarian tendencies well before the revolution was even won.

Could you expand on your second paragraph - I'm not sure I understand your position. Are you saying you think we're not able to provide for basic necessities with our current level of technical ability and available workforce?

Our ability to do this is more of a fact. But the socialist distribution system completely destroys this ability.

If you're willing, could you go on (expand your point), or link to a treatise that supports your position?

Do you think perhaps there is a reason why any communist regime quickly devolves into a totalitarian dictatorship?
