I went to a fancy “elite private prep school” during high school. The tuition was insane (comparable to some universities), but they gave out around 7 million in financial aid every year so there was a good mix of both wealthy and poor students.
I definitely noticed a lot of the mentioned things going on (by myself included). Mostly things like paying for food/snacks when going out with friends.
From time to time I felt guilty about growing up in a wealthy family. But it’s not my fault for being born, right? That was the main motivation for helping out my friends. If I have this privilege, I might as well use it to to help the people around me who aren’t as fortunate - even if it’s only through small gestures.
