Instead of being lazy, why don't you google the question? Even a simple query like 'jewish discrimination college' will give you materials to work with, ranging from US immigration policy restricting Eastern Europeans to the SAT being devised for reducing Jewish enrollment in elite universities, and if you go far enough afield, you will find gems like the 'Jewish questions' (compiled in a paper on ArXiv) that Soviet Russia used to block any but the very most brilliant Jewish mathematics students from higher education.
