College will already be made free in due time but it won't be from a government funded university. It will simply be from a private organization making the courses on their own and putting them online for free. People won't believe this but the technology already exists for it to occur. Most of college is simply organized textbook reading, with lectures, homework, exams etc. All of which can be digitized and delivered over the internet. Homework and exams can be digitally graded. Final exams can be proctored at a testing center like prometric. This system will deliver essentially the same results as a traditional university.
