You're trolling right?
I genuinely thought this was a real post at first.
But the responses you're having are just a little too cookie cutter...
Let's say you are a real person and are having this problem. First, congrats on making it to a setting that exposes you to a large number of peers from all kinds of socioeconomic backgrounds.
No matter how much money I have in my life, I think I will insist on sending my kids to public school. That's what I did for all my life and I turned out fine. Just being exposed to everyone else will really help in maturing and having broad life experiences.
You're taking the piss.
But there is some amount of genuine truth to this simple statement.
