That capitalism is not the cause of most societal grief. Pathological self preservation is a fundamental human problem. It’s the reason we’re okay with seeing hordes of homeless people, or with killing people to resolve geopolitical issues. Greed can optimize any system to work for itself, people who are or will be adept at such optimization would thrive under any kind of socioeconomic or cultural system, including extremely leftist systems. Just spit ballin’ tho, haven’t thought about it much tbh.
