Making college free will turn it into 13th, 14th, 15th, and 16th grade (community college is close enough to that as it is). It will not change anything because the teachers will be just as good as the economic status of the jurisdictions they are teaching... They will have districts, it will be runned by the county or jurisdiction, there will be regulations where people can go and where they can't. You think that Bernie is all of the sudden going to make Harvard or Yale free?
The problem with education is the donations received from fund raisers, extra curricular activities, mostly from the people that live in the area. If you live in a poor neighborhood, you get the worst teachers, the worst books, the worst schools, less oversight, and nothing ever changes. Free college is nothing different than extending that problem to later years in life. Is that what everyone wants?
I believe in competition, it makes the world go round. The only thing that hurts people is patenting the wrong things, and then taking advantage of that patent by pricing it so high that it is unattainable to the people that need it to survive. Like drugs. Now this is where I feel like a democrat, I point out the wrong but have no feasible suggestions to improve or change the situation, because the people that put a boatload of money into that R and D, should come out making a good amount of money on their investment, but if we make available to all at a low price, there is no incentive.
It's a catch 22
