All of the negative comments on here treat "college" as if it is one unified thing, when in fact the experiences across institutions (both educationally, as well as financially) are quite different.
All of that said, to those who say "free college": try telling that to a person in the middle of the state, who has never been to Madison, has never had a kid go to Madison, and who has to pay their tax dollars to support the University. It is a hard sell. Sure, it'd be great if people were willing to support colleges so that they were free. But the taxpayers, by and large, aren't.
