The solution though, isn't to stop providing money to students for college. If you don't have Pell Grants, Stafford loans and the like, lower income bracket individuals would never be able to afford college. There is a simple fact: I could not pay my way through my Midwest university education without these things. I will graduate and be in debt, but I'll be better off having done it. Certainly the experience is worthwhile.
The solution though, as some people propose, is not to end subsidies for lower income individuals. I see several people putting forth the argument that people are the most efficient at allocating money for themselves. That is not true except in an Ayn Rand novel. If people were so rational, everyone would go to college because the expected value of college still dwarfs the cost of college. Even for those individuals who would graduate with a significant amount of debt, it is far more worth it to have a degree than not.
So, how would a society reduce the cost of college education without removing the supports that enable low income individuals to enroll? Instead of giving colleges free money, we need to re-orient our structure of providing support for students that need it so that the college has the right incentives. For example, tying the cost of college to graduate's earnings.
Right now, a university gets money merely for pursuing higher levels of enrollment. There is no financial incentive for the university to involve students in student organizations, in leadership roles in their community, in politics or in networking. There is a tenuous link between those activities and pursuing alumni programs, but from what I've seen, alumni programs are a post-hoc solution to funding. A university sees an alumnus has done very well, and seeks to share in their wealth.
Let's simplify: the cost of a college education is 3-5% of aggregate gross income for the rest of your life. People who go on to be tremendously successful will benefit their university, and the university will have an incentive to churn out more tremendously successful people. This tax could be enforced by the IRS, automatically deducted in most cases, and manually reported elsewhere.
Now no one has to worry about the stress of student loans, and universities have every incentive to provide the highest quality education possible to maximize the value of their students. No more flooding the rosters of the university with under- and unqualified adjuncts in order to support higher enrollment numbers at lower costs to pad the pockets of administration. No more cutting student involvement to pad the athletics program.
