education
The average student does not exist.
I'm 21 years old now, and I have spent two thirds of my life being educated. My brother is 17, he's spent 11 years being educated. There was a reform between us, so he's been in public school one more year than I had when I was his age.
We have wildly different interests, but we still agree that most of what we did in school was a waste. The same goes for practically everyone I know. I think that for every Norwegian youngster you find that liked school (The educational part of it), you will find five, or ten who didn't.

Alex Tabarrok points out some interesting stuff about education vouchers, but misses a key point.
