<p>I’m not entirely convinced that it’s Ivy league schools that makes people “successful”. Consider the kind of students who get into Ivy league schools - they’re either ultra-rich or entitled OR they’re bright, hard working, determined, and lucky. You have bright, hard working, determined, lucky students at many schools. But if they’re concentrated at a small set of schools, especially at schools great at providing opportunity and a great education, then you’re going to see a disproportionate number of “successful” people from those schools.</p>
