OP’s daughter’s friend can look at Princeton or Stanford all she wants. As others have pointed out, only a tiny percentage of QB Finalists are matched - and most of those, judging by the narratives posted on this website, live below the poverty line and have incredible personal stories of overcoming hardship to excel academically.
As for “cheating” and “not deserving” QB Finalist status…my son was a finalist last year: white male, family income over $60,000 the year he applied. He’s the oldest of 5 kids, but that’s about his only hook. We certainly aren’t even “upper middle class,” let alone wealthy, but it’s not like he’s had financial hardships to overcome. I suspect we were on the far end of the income range for QB at the time, but he was selected without cheating.
