Malcolm Gladwell has an essay in the New Yorker about how the admissions process at Ivies such as Harvard have evolved. Turns out they added character and physical evaluation in the 20's as an Anti-Semitic reaction to the increasing number of Jews enrolling. Also, it bugs me how income is often used as the only metric of success for college graduates in these kind of studies. Maybe I'm biased since I don't see myself making near six-figures any time soon...
