Capitalism is a system that rewards sociopathic behavior, so sociopaths with no empathy or investment in anything other than themselves naturally rise to the top.

The oligarchs who control our nation are all mentally ill narcissistic sociopaths who don't care what happens to the country or to humanity or the earth after they're gone. Life to them is a story where they're the main character and everyone else is an expendable NPC.

This is why capitalism is considered unsustainable to anyone other than those who idolize the oligarchs and wish to become one themselves. This is why hierarchy and class is something we should be trying to eliminate from society, not lean into even further. When human ego and individualism is allowed to be the cornerstone of human society, it is a matter of when, not if, that society eventually crumbles to the long term effects of wealth inequality.
