A professor in my social circle has taught at various schools across North America including Harvard, University of Toronto and a few prominent USA state schools. He says in his experience there's no difference between the intellect and quality of work he sees at the schools he's taught at but the Harvard students are more ambitious and more entitled.
In my own personal experience Harvard, Princeton, Stanford types often carry an elitism that they need to justify the work they put in to get to that school and the amount the school prestige means to their own self worth.
There's also a classic OpEd from I believe the Harvard Crimson from a Harvard admin officer saying Harvard could admit sufficiently qualified students from it's applicants several times over the actual count of its freshman class. So basically you have to have rich parents or be lucky not just be qualified. The elitism exists nonetheless and it's a fraud.
