I think that a student’s response to being surrounded by lots of wealthy peers varies not just by school, but also based on the child’s personality. This is conjecture on my part since my oldest is only a college freshman so I don’t really have a point of comparison yet. But all of my kids have attended K-12 schools on significant financial aid, and I think their response to income disparities within their schools has varied based on their individual personalities more than based the schools’ cultures or the wealth distribution within the school.
I do have one kid who wants a high income career and (I think) has always been somewhat frustrated by having less than many of her friends. I suspect her career goals are a reflection of never feeling like she has enough $$$ to socialize with her peers. On the opposite end of the spectrum, I have one who doesn’t seem to care at all about “keeping up with the joneses.” Perhaps for this reason, I’ve noticed that the kid who cares the most about “keeping up” has friends and classmates over a lot less than her siblings. And when she does have people over, it seems more likely to be friends who are middle class or below. My other kids don’t seem to mind or even notice when having their super-rich friends come hang out or sleepover in our small cramped apartment. To be honest, when my kids were little and I had more frequent contact with their friends’ parents, I also felt some level of embarrassment and discomfort when I interacted with the families or I was a guest in their homes. So maybe my money-conscious kid picked up on my discomfort more than her siblings did.
On the other hand, I have heard my teens remark on their bemusement (and sometimes amusement as well) about how entitled some of their friends are. I think they are less annoyed by the kids from very rich families than by the kids from upper middle class and wealthy kids. As my son put it, the really rich kids know that they are rich and lucky. My sense is that my kids think many of their upper middle-class friends are unaware of just how relatively fortunate they are. I don’t think my kids know this expression, but they describe some of these classmates as having a sort of “born on third base but think that you’ve hit a home run” kind of attitude, particularly around their academic achievements. And that attitude bothers my kids more than the actual gap in income. I don’t think any of this rises to the level where my kids have wished that they attended different schools and I am not sure that it will impact their college choices, but they do have a kind of impatience with peers who are unable to see how much their parents’ income helps and protects them.
