LOL, you don't know how hard it is for me right now NOT to write a novel in response to your astute observations! So I'll keep it brief as possible...
1) Me and ALAYWIFE have parlayed our local podunk university bachelor's degrees into reasonably successful professional careers, but, ALAYBOY doesn't have a lot of common sense when it comes to receiving this kind of wisdom, and consequently wants the "big boy" academic prestige (yeah-yeah, I know, if he transfers then the degree he holds doesn't reflect those first 2 years of Podunk U, but we've told him that too)
2) He is planning, as of now, to go to medical school, and thinks BIGBOY U gives him a better shot at entrance. That is subjectively true, but certainly not as clear-cut as it might have once been.
3) He's a good kid, and who can guarantee that isn't corrupted at SATAN U BIG CITY, but in his defense, he ain't much of a socializing type, and doesn't exactly fit the profile of one susceptible to the wiles of the party life.
4) We've told him about saving money by going the satellite campus to BIG CITY U, whereby we could save money, but hey, he's spending our money so who cares, eh?
5) PODUNK U that mom and pops graduated from fits nicely with your theory of smaller class size and more professor-student access, but ALAYBOY is a wet-behind-the-ears-greenhorn who doesn't have a clue about such common sense measures. Through ALAYWIFE's connections we actually got him a personally chaperoned one-on-one tour with the head of one of the science departments at PODUNK and she explained this smaller class size and professor accessibility thing, but he's got blinders on. To make that one worse, PODUNK has a special relationship with Ohio University to ensure a way into med-school (assuming minimum prerequisites are met throughout the undergrad journey) and there's no necessity to take the MCAT.
