I actually don't think it's particularly weird. I would cite various research on studies investigating "fairness" [0] (Citing this one re: corvids since I need to get back to work and this was a quick google, but it chain-cites papers in primates, dogs, humans, found what appears to be a meta-study here [1] as well) Namely, that individuals will decline to participate in exchanges where they would benefit, if another individual would benefit inequitably. I think you sell short the systemic advantages by framing it as "Feces-hurling"; namely that it may serve as an important societal and evolutionary pressure, for instance, as [1] suggests improved social cooperation. Some of the comments on this thread even touch on this, although I'd frame it a bit differently, with comments such as "many people find the existence of a billionaire implicitly unfair." Namely, judgements of morality, economics, society aside, one has to be rather stoic to feel _no_ envy when comparing ones own lot to the life and resources being a billionaire enables, so that it would trigger a "lizard brain" instinct seems entirely natural. (and again, similar to you, trying to keep this argument-free WRT the contention around that and making a meta-observation, one may disagree as to how justified or sensitive one should be to this feeling, I'm just pointing out "I can understand it on a very pragmatic level.") We may be agreeing loudly here, my response is primarily to addressing your stated surprise, as well as try and paint the cause and effect in a more... detached? perspective, to better contemplate its nature and incentives.
