I don't know how to respond to this because it's clear it would be an uneven conversation. You're missing very basic required knowledge here. Inequality, for instance, is at its highest point in recorded history. Capitalism is a form of authoritarianism. Economic conflict turns into military conflict which increases the risk of nuclear war. Capitalism is not human nature; it's actually pretty recent and radically different from its precursors in several important ways. I have no idea what you're even talking about regarding communism or how it's even relevant.
