I question that analysis. High status can certainly create a sense of entitlement in some people, like how rich people generally leave awful tips, but at the same time you can see a sort of noblesse oblige in others which leads to huge charitable donations and voluntarily forgoing chances to improve their position (like sending their kids to public schools). Low status people generally have a lot less to lose and thus tend to be a lot more pragmatic in my experience.

Interesting question. I definitely feel high-status. I'm in a high income percentile, and have substantially higher net worth than that most people with my income history, because I've made good decisions about how to use my income. Obviously, I know people who are higher status and wealth than me, but I mostly compare myself to people who are not. (Partly a deliberate choice to try to boost happiness and life satisfaction.) There might be a status connection. To exaggerate, it feels more like "someone of my status shouldn't stoop to grubbing around with low-status arguments about money" rather than "someone of my status doesn't deserve money". That might be a contributory factor, but it feels like the effect size is small. In the negotiations I feel regret about, I definitely felt like the higher-status participant, but the less experienced at negotiation. Or rather, the less effective one.
