I think this is school dependent. In my experience, many wealthy kids will hide behaviors they know are associated with being wealthy / hide their backgrounds in order to better fit in. The awkwardness goes both ways.

Middle class kids might, not upper class wealthy ones not so much.

This is highly dependent on university - I didn’t notice it much where I went (RPI), but it’s a lot more obvious at Stanford.

Not all of us went to schools that have "much wealthier people" attending, of course.

I find that hard to believe unless your country has a very stratified higher education system - which is a bad thing.

Well, my country is the US, and I am speaking from experience. I'm definitely not saying it's a good thing. It's just important to acknowledge that "the college experience" of elites and the elite-adjacent doesn't represent the common post-secondary case here.
