Beautiful points. To add to them, I highly doubt that people who truly want failing to go to college due to the cost of college is common occurrence. Student loans are relatively easy to get, much financial aid is need based, and if all else fails the military will pay 100% tuition in most cases.

I do know of people that had to leave college in order to financially provide for family members, for instance an unexpected pregnancy, but that is different than the cost of college itself being a problem.
