In these conversations I always get to an impasse because yeah, capitalism is very flawed and produces many horrible outcomes. But communism has failed to work at all (as far as I know). Last I spoke to a communist as passerby was asking for what my conversation partner thought was a example of true communism, to which the answer was "the very start of the Russian revolution". I won't pretend to be the most informed about history, and I know that there has been much interference from capitalist countries, but if communism were so clearly a better system would it not have stably worked at least once? I'm having a hard time understanding why that's a better goal than the countries that seem to reign in capitalism with at least some success.
