I support it by the fact that the graduate programs in CS at all of those schools are much larger than Brown’s (and garner more institutional priority in particular at MIT, Berkeley and Stanford) and based on the employment and grad school history of Brown undergrads. In particular the voraciousness by which tech companies (Facebook, google, adobe, microsoft, apple, pixar, you name it, etc) descend on campus like the wicked witch’s flying monkeys trying to snatch up all the seniors with their various competing offers. I remember senior year everyone talking about the recession and how hard it was for college grads to find jobs and trying to reconcile that with my CS/finance friends getting actively recruited by all the top companies in their fields and trying to decide which of the multiple offers they were receiving should they accept.
