What's the purpose of education?

Over at Marginal Revolution, I found this pithy piece:

I view education as a self-commitment to being a more productive kind of person. Education is about self-acculturation.

Men are born beasts. But education gives you a peer group, a self-image, and some skills as well. Getting an education is like becoming a Marine. Men need to be made into Marines. By choosing many years of education, you are telling yourself that you stand on one side of the social divide. The education itself drums that truth into you.

Similarly, if you become a Mormon or a Protestant in Central America, your life prospects go up. It is not that Mormons have learned so much more, but rather they have a different sense of self. They have a positive self-image about their destiny in life and choose a different set of peers. They also choose not to drink.

It's an interesting idea - that education might be more important than we realize. It's not "just the facts" that matter, but the opportunity to mold CHARACTER.
