I think the comments on the quality of the alumni network are spot on. This is something I had not realized until after I went to Marquette for grad school. The alumni network from my decently well respected regional undergrad university did not have nearly the passion or emotional connection to the school or fellow alumni that Marquette does and the results of that are stark.
This has come into play in a remarkable array of areas in Life. Personally I’ve benefited in such ways as job hunting, business networking, house hunting, buying a car, finding a good baby sitter, making connections for entertainment events, discount on a new water softener because the sales person's son was going there, opening lines of communication with other parents at my kid’s school, and many more. Being a Marquette grad has enriched my life in ways that these USNews rankings just does not account for and high school kids, for the most part, are completely unaware that some schools have these types of intangible benefits. It is very unfortunate.
One small note on the ability for any kid to get a good education at a State Flagship university if they wanted; can we strike Arizona and ASU as exceptions from that? Woof! My experiences with any alumni and students from either Arizona school has been… let’s call them, “less than stellar.” Maybe I’ll make an exception for ASU’s engineering school though.
