The question up for debate is...
Should public college be free of cost, or would it create too much liability?
My side: I take the stance that yes, free tuition of public college would indeed be best for society in general. It could be costly for government. And it could cause other problems which need to be addressed as they spring up. But one way of paying for it is, if more people go to college, they make more money (in a perfect world), then they have more money that can be taxed. So not only do you potentially end up with a more educated society, but in the long run, there's the hope that free public college will eventually pay for itself by someone's potential 20+ years of work before retirement, should the average be that high, and the additional tax dollars picked up along the way from the higher salaries of said workers.
