As a person from X farm town...probably 50% of my HS graduating class went to college and most of those went to trade school or community college. I don't know of anyone from my town who ended up at an Ivy League or other highly prestigious institution (unless you count Ohio State...). I know of 2 people under age 30 from my hometown who are in medical school/physicians (I'm one of them). There is also a lot of discouragement in certain families for women to work outside the home...when I go home, I am asked WAY more often if I'm married yet than about how medical school is going. And my high school was definitely a bit of a joke if you're above average intelligence...my high school didn't have AP classes or many other options for advanced students, for instance. I was definitely not as well prepared for college as I could have been in some areas. Efle isn't making a comment on the ABILITIES of rural people, but a comment on the OPPORTUNITIES for rural people. So I'm not sure it's stereotyping because it's not about the people, it's about structural issues.
Skipping ahead to my medical school class, there are 4 of us who are from rural areas and 3 of us are strongly considering rural practice in much needed fields (primary care and EM). I don't know what the 4th's plans are. I also agree that one of the best solutions to the rural physician shortage is to make medical school more accessible for rural students.
Also, I legit do not understand why everybody thinks it's so boring to live in rural areas. It's really not that bad, especially if you're into the outdoors. There is plenty of stuff to do - 100x better hiking, fishing, kayaking/canoeing, and literally any other outdoor activity than the cities. There are restaurants around, but they're all locally owned instead of Chilis. Plenty of cool skill workshops and historical lectures and stuff at the local library or town hall. And it's not that bad culturally either - you'd be surprised how many cultural festivals (to be fair, mostly European cultures), concerts, art/craft shows and stuff there are. And if I wanted to do a day/weekend trip I can drive a couple hours to get to some major regional cities with more stuff that you "city folk" tend to enjoy 😉 But I'm just as happy to head down to the river and try to catch some bass if it's nice out.
But yes, not very diverse, mediocre education, etc. is all accurate.
