College is a knife sharpener. If your knife was already sharp or you figured how to sharpen it on your own and how to convince other people of this fact, you don't need it. Most people need it, because they can't do all this on their own. Furthermore, some of them have such good steel in their knife, that sharpening will be a great leap, and it would have been a waste, in some sense, to miss it. The tragedy is that we convinced everyone that they NEED the sharpening to have a good life, even if they have tin knives, as if a sharp knife is the only tool.
