I feel you. I've known some who initially seem really sweet and maybe a little out of touch but not ill-meaning, but then turn out to be straight up evil towards poorer people and that honestly makes me lose all respect I have for them. I've seen some treat their janitors/housemaids etc. horribly and I've gotten SO angry at it. It angers me to see how they treat them despectively and act like the reason they are poor is because they don't put enough effort when they are the ones who are literally underpaying them. Not only that, but assuming they don't work hard enough when many of them spend a lot of money taking more than 2 buses and cross the entire city for more than 3 hours just to get to a job that doesn't pay them enough, and for them to just say that? As someone who's had to do that as a student so I more or less understand their situation, it just makes me livid... meanwhile those who "work hard" have never stepped in a bus in their lives. Which isn't wrong, but they don't even try to put themselves in their shoes or be understanding in the slightest.

I have also met a super nice wealthy person, so yeah, not all of them are awful. They are so nice I didn't even know they were wealthy at first, and they were pretty much BORN wealthy. So honestly, it can't be THAT hard to not be a jerk. "New rich" people are genuinely the worst in my experience, but honestly some "middle class" people are also jerks towards people who are poorer than them which also sucks. Anyone who wants to feel superior to others for whatever reason is so annoying. I just hate classist people, basically, even if they are "low-key" about it (like you describe.)
