I haven’t looked, but I bet you are wrong about that. There’s Wharton, of course, and the business program in the College Formerly Known As The Ag School at Cornell, and Course 15 at MIT, but all of those have a very different philosophical approach to undergraduate education than the University of Chicago. There are lots of colleges with undergraduate business schools, but they don’t count for these purposes; they haven’t spent the last 125 years pontificating about liberal arts education. On the CTA system, Northwestern has some sort of Kellogg certificate program, but it has very carefully stayed away from any major that is labeled “Business.” Most critically, you are not going to find anything remotely similar at Harvard, Yale, or Stanford . . . the crew Chicago usually likes to hang with (except for sometimes adopting a holier than thou attitude about their supposed pre-professionalism). I’m guessing that Columbia and Brown are similar.
I bet you are wrong about that, too. Not necessarily about HYPS – I think that statement would be accurate, or close to it, as applied to my class at least – but about the University of Chicago. The number of UChicago graduates applying to medical school or law school in any year doesn’t begin to approach a majority of graduates, much less a “vast” majority. According to the "Careers In . . . " website, about 100-125 students and alumni apply to medical school every year. Some of those are likely repeats, and they are not all successful. They used to, but no longer do, have numbers on law school applicants, and they weren’t much larger than that, maybe 150, not all of whom actually went to law school. They don’t have business school application numbers, either, and those would be trickier to follow anyway, but there would have to be a heck of a lot of them to get anywhere near your blanket statement.
Anecdotally, my kids’ UChicago friends include one MD (my daughter-in-law), maybe three lawyers so far, and 0 MBAs. Then there’s a friend’s child, whom my kids despised, who’s a JD/MBA. Most of their friends have some sort of graduate degree at this point, but it’s generally not in medicine, law, or business. I’m sure they’re not precisely representative of the average UChicago experience, but the difference vs. my experience or my wife’s (from a very different social circle) is really striking. Of all the people I ever roomed with – n = 12, counting me – the only ones who didn’t have a JD, MD, or MBA eight years after our graduation were two who never finished college because of substance abuse problems and a computer science major who was also schizophrenic. The equivalent for my children, combined, same n = 12, is 0 of such degrees. And no drop-outs or diagnosed mental illness.
