I wanted to add something to your list. Although this characteristic is not only held by some rich people. My pet peeve is making negative assumptions about people based on very little information. Here you have a guy who just made a polite comment seemingly to be nice. You know nothing about him at all and yet it’s somehow evidence of his….I guess privilege.

I lived in a very wealthy neighborhood growing up. So on the surface I appeared to be one of those wealthy teenagers. In fact I slept on the couch of my grandparents studio apartment that was a converted garage space because we were poor.

Assuming you know someone enough to make negative assumptions because of your fleeting observation seems a bit pretentious.
