Earlier quoted context omitted.
One of humans' needs is for status which is by definition zero sum. Same with mating. If anything those two are probably the most important needs so it's not possible to build such a system.
If one of human needs is status and status is zero-sum, then why does it matter what economic system is in place at all? We could equally rely on feats of strength, or games of chess, or rolling dice for all I care. Besides why can't one of human needs also be an economic system that doesn't have the failure mode of poverty?
Those aren't very productive, our current system makes people produce value for others in their chase for status. Older systems people destroyed value for others in that chase, creating wars or other miseries, we have much less of that today.
I'd much rather have another billionaire than another authoritarian warmongering dictator.
