Based on the U Wisconsin map, that appears to be incorrect. By far and away, the most students are coming from Milwaukee - and WIsconsin has many urban areas.
Additionally, they’ll be loaded with Chicago kids and others from the NE attend U Wisconsin. 1167 alone come from NY and 820 from NJ + 2243 from California.
Sure, some will be from rural areas - but do you think that would be different at NU? I don’t think so. Maybe fewer but they’ll have them too.
Statistically, I’m not sure your hypothesis holds weight. For example, Indiana is much closer than NY but only 209 are from there and 197 from neighboring Iowa. NY / NJ are much farther and much more impactful at the school.
As for careers, given the hiring today is often done over the Internet, that’s also not an issue. My kid went to school in the South and had 19 interviews - including a few in Wisconsin - and ended up out west. The internet is the great equalizer. You can get a job in any region, from any region.
If you don’t want to go to Wisconsin, don’t go - but I don’t think that your arguments hold weight as to why not to go. If it’s just you don’t like it, that’s reason enough.
Good luck.
