Nobel Prize-winning economist/columnist Paul Krugman warns of American education in decline.

There will be a post forthcoming about the educational system in Korea, but the Korean will say this much for now: he moved from Korea to the U.S. at the age of 16 without knowing much English, and graduated second in class from his high school. It is extremely unlikely that the same outcome in the reverse direction would have been possible. The Korean's high school in Korea had a number of students who spent their youth abroad -- none of them escaped the bottom 10th percentile of the school.

To be sure, Korean educational system has a ton of flaws of its own. But as it stands now, it is vastly outperforming its American counterpart. As an American, the Korean worries.
