There's been a lot of talk lately about the higher education "bubble".  Glenn Reynolds, among others has been on this case for several years now.  Shortly after Richard Levin and maybe a year or so after son John matriculated at Yale in 1990, I wrote Levin a two page letter questioning the cost (the about $42,000/yr) of a year at Yale and suggested one of the reasons was the comparative size of the course curriculum catalogue -- at least two-times thicker -- between my years at Yale ('54-'58) and John's.  Levin wrote back in a lengthy letter that a world class university must keep up with expanding knowledge and for that reason Yale must continue to offer an expanding number of courses and fields of study.  Somewhere along the way in an office move I lost that letter which I would dearly love to read again in light of this post from Powerline today.
