Harvard has better academics, but there is not a huge gap in the quality of education for an undergrad degree. They are both part of the upper echelon of academia. Yes you can go to harvard undergrad then michigan grad school, but you can also go to Michigan undergrad then go to harvard grad school...Really what it comes down to is how hard your going to work. If your determined and get into both schools then you will excel at either place, which will pave the way to do what you want.
