It would mean that bigger monkeys are capitalist and smarter people are socialist.
Ultimately, I think it's about ability. The study focused on physical ability, but surely, intellectual ability, or even merely a decent work ethic, is just as relevant.
Whether physical, intellectual, or ethically, I think it very obviously stands to reason that those of low ability,or those who perceive their ability to be low, will be most likely to favor a system in which they can ride on the backs of those with greater ability; while those of us with greater ability will much prefer a system that does not burden us with carrying the low-ability parasites' load along with our own.
