I'm not sure what reciprocity deals are in place now with neighboring states but in theory, for surrounding states, that should balance out. I can't imagine those schools are seeing many students from outside the five state region.
As for private schools, that's another matter entirely. Most are WAY overpriced. You will never convince me that with the possible exception of Carleton and maybe some specialized programs, that you are going to get a better education, much less ROI, attending an MIAC school over a state university.
