People that see (growing) wealth inequality as a problem rarely perceive themselves as part of it, but e.g. anyone complaining about the "top 1%" on this forum is pretty likely to be part of the "problem" themselves, globally speaking.
I think that for a lot of issues "people richer than us" are mostly a convenient scapegoat to shift the blame upstream, e.g. with CO2 emissions: If you're an average "western" citizen, then you are pretty likely to be in the upper percentiles of emission culpability, and pointing at celebrities and their private jets or somesuch is no better than thinly veiled whataboutism in my view.
