I genuinely don’t know what you mean by Communism requiring everyone to “act in good faith.”
What if someone doesn’t adhere to ‘From each according to his ability, to each according to his needs’? We can go and imagine a real utopia, but there are very real ways it can go wrong and the system will have trouble handling it.
The main thing I am arguing though, is that communism doesn’t really account for imperfect behaviour. At the moment, no one system does.
The system definitely encourages and rewards explotation, but why do people do it at all? Will this behaviour stop if we penalize it? Or just gently teach the children after the bloody revolution?
How do we get past the notion of power corrupting people? All I’m arguing is that communism is not an outright solution for society.
I promise to read up on dialectic materialism, but the end of link you sent mentions getting a gun. That’s just bad advice.
