the idea that college is necessary is a relatively recent aberration that from what I can tell dates back to the end of WWII and the GI Bill. before that, going to college was rare.

college is not for everyone (we need good plumbers and auto mechanics, fer chrissakes). i didn't apply myself as well as i could have at college, but about 40% of the value I got was from reading interesting books I found in the library, which I could have got for $100 a year while working in the real world and gaining money and experience -- which is what I'm doing now.

that said, some things are very hard to learn outside of a classroom and the mathematical maturity I gained from taking math classes will serve me for a life time.
