Getting a four year college degree is a mandatory rite of passage into the middle class these days.
It almost doesn't matter what you do as long as you get the piece of paper and you can move on with your life. Everybody's incentives are aligned: the school will graduate you and make their money, the students will get their degree, and eventually a job, the employers.. well, not sure, but I guess they'll filter for the signal that their candidate is able to complete something long and tedious.
