Yes indeed. You "explained" it by completely ignoring the loss of scholarships and financial aid, and completely ignoring that a very great number of people don't have the means to move to another location for school, nor to pay out of state tuition.....
Most students do not have scholarships. Most financial "aid" is in the form of loans which students can get just about anywhere. And many areas have more than one schools. And there are online courses. If someone really has to have a specialized degree or some specialized "career", then they will move to find the program - otherwise they really don't want it. And, of course going to prison and surviving it generally reduces the scope of one's legal life choices upon release - especially if one is imprisoned for rape.
Would the results of a random survey of college students and ex-cons who are asked "Which would you prefer - expulsion from school for improper sexual conduct or imprisonment for rape?" convince you that your position is based purely on ignorance of the reality of imprisonment and the current higher education market?
