I think this is harder to see if you grew up in a nice area, with educated upper-middle class parents, and followed the traditional college->office jobs path. Or conversely, it’s hard to see if you didn’t grow up in that kind of life but were never appreciably immersed in it. We have a social contract that strongly discourages punching down so I’m trying to be delicate here… but if you spend a significant amount of time with poorer people you find that negative personality traits (to the point of being pathological and actively harmful) are much more common outside of relatively “elite” circles than within.
Any sort of institution that is “picky”, including most good jobs, naturally selects against moderate-severely negative personality traits. If someone shirks all responsibility or work they’re unlikely to have a meaningful career unless a family member swings them a sinecure. If someone is overly confrontational or aggressive they’ll get fired from their jobs. If someone is unable to take blame or accept feedback they’ll never develop appreciable skills. By all means I’m not saying well-off/famous/affluent/accomplished people are all virtuous or good people, simply that those who do so on their own merit typically as a group lack major personality flaws, which actually may resemble something of an “inner-ring” to those who grew up/live outside those circles where those traits are more common.
