Look, some in state options are great and much cheaper than the vast majority of private med schools out there. Some are not great and not much cheaper.:
I disagree with this statement about some being "not great". Though possibly true re: liberal arts colleges, medical education is so standardized in North America (US and Canada) that the difference in educational quality between high and low ranked schools disappears in the face of the differences in student motivation within any given school. While Harvard may have more Nobel prize winners, being a famous researcher does not make one a great clinician or a fantastic teacher, and some of the state schools, often connected to large public hospitals, often offer the best clinical experience.
I went to Tulane Univ Med School, and when I was there (late 1970s) it was consistently ranked as one of the top twenty in the country. We shared our major teaching hospital (Charity Hospital, New Orleans) with LSU Med School, consistently ranked in the bottom twenty. We also occasionally shared clinical rotations with LSU students. As far as I could tell, our education was not significantly better than theirs, nor were our students significantly better (remember, even the lowest ranking schools are very competitive, so on the whole, wherever you go, you will be surrounded by bright and highly motivated students). Their training was somewhat more"primary care" oriented whereas ours was a bit more "specialty" oriented (state schools like candidates interested in primary care since most states have shortages of primary care docs), and on that basis, one might choose a school based on career goal.
Both schools offered far more "hands-on" cinical experience (day-to-day operation of Charity Hospital in New Orleans was pretty much run by the housestaff) than did places like Harvard. I did a rotation at Boston Children's Hospital (Harvard's flagship pediatric hospital), and it was a wonderful experience...we saw some amazing rare pathology...but I was astounded at how little the students were allowed to do...we were not even permitted to start IVs! When I did my internship at Royal Victoria Hospital (McGill Univ.'s teaching hospital in Montreal), I was running codes for 2d and 3d year ER residents who rarely saw gunshot wounds, stabbings, etc. and lacked my experience. There was so much trauma at Charity that first year med students would stay up all night in the ER sewing up wounds, and 4th year medical students were performing surgeries that only a lucky 3d year surgical resident might be permitted to do at Mass General .
Tulane probably did make me a bit more competitive for residency programs than I may have been had I graduated LSU, and I bet Harvard would have made me even more so. But I doubt that the "pedigree advantage" was anywhere near great enough to justify additional costs (I paid in-state tuition at Tulane), I am sure that none of the three produced consistently better doctors, and a student who distinguishes him/herself at ANY school will make the interview stage, at which point "pedigree" becomes nearly meaningless.
