when college is free, it becomes worthless. if you have no skin in the game, ie financial interest, what incentive is there to get out of school and get a real job? all its going to do it prolong childhood for another 4-8 years for every "student".
The benefit of college is learning how to be an adult, and function on your own, and that entails working a job, balancing finances, school demands and social ones also. You get a book education, but you also get a life education with training wheels. What will be the incentive not to cheat your way through? Because now its free and who cares if you learn anything. What good to society will students be after college?
The government currently taking over the student loan industry has destroyed higher education as it made college tuition skyrocket.
hell, as it is, college isnt free but there are more stupid "college educated" people out there than i can shake a stick at. AOC may be the most famous and dubious example. 2 degrees and tending bar and selling coffee. thats whats happening everywhere. English and History degrees because they are easy and free, and then the minimum to get any job, any job as menial as dock loader will require a degree. because essentially, every person with a pulse will have one.
