True, but only comparing state schools is probably unfair. We don't have the same caliber of state school because of funding. But we also have a ton of fantastic private school networks with net tuition close to most of their out-of-state tuition prices. Or at least not terrible. Face-value tuition is going to be higher of course.
I think the environment is probably more a factor... private schools are cool, but for kids that want the big state school environment, UConn is definitely expensive compared to down south. There's no way you could graduate undergrad up here with less than 30k in debt like my fiance did, especially from a school ranked as well as UNC. It's unheard of.
I really doubt that the kids coming from your daughter's school are going to be concerned about price though. How many kids your daughter graduated do you think are actually paying for their college? (Honest, not snarky question... I know there are plenty of private school kids not flush with cash). I would imagine weather, sports, culture, and getting away from home are the factors here more than price. UConn is in the northeast but isn't pulling the kids that like winter sports, but the weather isn't good enough for someone who wants to see the sun. It's sort of a crappy spot to be.
UConn needs to work hard to boost its ranking though. #63 in US News (and around there elsewhere) is fine, but not a draw for talented students in itself. I know a few departments are making big strides right now (education, philosophy, bio, and I think the pharmacy school?). Hopefully, an improved basketball team will help. I know the rankings are not very meaningful in a lot of ways, but having a top-50+ public school in the northeast would be pretty meaningful. A better ranking could pull some of those super-smart kids that are all heading to Wesleyan, Tufts, Hamilton, and the like right now.
