While this is a very crass over-generalization, I've found you really see this in the graduates. I've found Ivy league school graduates to be sort of... disconnected from reality? Like experts in education who clearly don't understand any of the on-the-ground realities of teaching (your lesson plan is beautifully structured, but we can't use it because it will make the students cry because they're 7). For the crowd here, imagine reading an academic paper about making improvements to production systems from someone who's clearly never been anywhere near one and is glossing over all the important fiddly details. It's like they've been told that they're smart and going to revolutionize their field and they can do so without ever having to get their hands dirty with more messy details.
To repeat my crass over-generalization, MIT and Caltech style schools seem to do a better job of instilling in students the understanding that if you want to change something you need to understand it, and to really understand it you need to spend time in trenches. I've been consistently more impressed with the results graduates from those schools get.
