This is VERY VERY true. I once posted a lot on Yahoo Answer's in the education section. I noticed in the US there is this cult of the Ivy's. Some do not even understand that schools like MIT and Caltech are as good as Ivy's - although most know that one. What is much harder is getting across there are often schools that beat the usual suspects, but most simply do not know about. For example in people going on to do a PhD Caltech heads the list, but just after that are schools like Harvey Mudd and Reed, even ahead of Harvard etc. Personally my favorite science school is Harvey Mudd ahead of MIT, Stanford, Harvard etc and I always mention those interested in science/technology consider this school. Yet many have never even heard of it. And in some areas like Industrial Engineering schools like Georgia Tech are often ranked higher. We have even had posts here on Physics Forums (deleted of course because it is misinformation) that when this is pointed out start calling those trying to give a balanced answer lairs etc etc - all in a very indignant tone. Its quite exasperating.
To the person asking what is top tier etc a much better way to choose a school is to post here with your career goals etc rather than look at rankings etc.
