A bit OT:
I must say, I'm rather tired of seeing studies that presume that income is the final measure of whether students succeeded, and therefore of an instutition's worth. By this measure, a student who got a BA in [Insert Gut Major Here] and then went on to make a lot of money doing something unrelated in daddy's firm is a glorious reflection on the value of the school, whereas my spouse, who has an advanced degree but works in public service in an undercompensated field (however, he would never have gotten his job without that degree) is presumably something of a discredit to the worth of his two graduating institutions.
