A couple of points:
1) I posted this here to spur discussion, not because I endorse a view that financial wealth should be the driving force in selecting a college. However, given that students are currently weighing a great many variables in choosing a college, and a variety of financial aid options, I do believe that taking into consideration the financial ROI of one's investment in a particular university is prudent. And, to that extent, I find the information reasonably useful.
2) I don't believe that what people make after graduation is primarily driven by whether they come from money. I've seen too many students of modest means leverage the power and prestige of a school's reputation into very lucrative professions. Doors that were previously closed were open on the basis of the university they attended, and to varying degrees, performance. For example, in my law school class, even students in the very bottom of the class were given job offers that only students at the very tippy top of other schools were offered. While I make no comment about whether that is an effective strategy for employers, it is the reality in some professions. And, knowing that you have that kind of cushion, one is much more free to enjoy the educational experience and not obsess over grades and class rank.
