While I pretty much agree with the sentiment, there's a bit of information that's missing from this analysis. I attended a high-tuition private high school, but I was far from rich. The only reason I was able to attend is because I got a 100% academic scholarship. A large number of students in that school were there without paying tuition, in fact: there were the academic scholarship kids like me, the athletic scholarship kids, and the kids whose parents worked at the school and therefore got free tuition. So you can't really just take the tuition of the school they went to as an indication of how much money they had at the time, without looking into things like grants and scholarships.
