I mean, in the simplistic case of monkeys, this doesn’t work because the other monkeys starve, which is a failure as a species.

The monkey would have to hoard just enough bananas that the other monkeys can still barely their basic desires, while keeping them hungry for more and letting them believe they could one day be like you and get as many bananas by working their way up an imaginary hierarchy, where the way to go up is to fuck over other monkeys and get you as many bananas as they can, while you give them the minimum possible share.
