<p>I don’t buy it. Its hard enough to find some one 30 years after graduation, let alone to have them spill their true earnings. So, lets say for the 1000 graduates from Caltech in class 1980, they found 100 and only 10 did not go to graduate school and 5 of those told the interviewer some kind of “salary” figure, but fail to report thier 1 million dollar capital gain or loss (on paper or realized). How could that be accuate representatin of Caltech class of 1980? How can we believe the figure being so close to each listed schools? In the Caltech example above, what about those 900 they did not find or unable to interview? This report is a total bull…</p>
