Hope I’m not thinking too abstractly here:
If you’re an individual with only their bare hands in a society that doesn’t need manual labor, not even necessarily a capitalist society, then that society would have to give you something (education) in order for you to give back to society. Once they do, you’d owe them. Maybe not dollars, maybe a moral obligation, but they’d only give you something expecting a return
“The rich get richer” through things like stock buybacks are their own issue. I just don’t get the implication this is a genuine multi-layer representation of an issue.
