From a national security perspective, I feel like the flywheel effects of the biggest universities are advantageous. I want to encourage emergent properties at as many universities as possible, and the idea that properties emerge at quasi-stable breakpoints seems pretty defensible. So if I want 10-20 at max emergent level, then I would be happy to also get 50-200 at max-1, 100-500 at max-2, and so on. Why do I care about thenet benefit accrued to any given student or students? At the limit, shouldn't I prefer to bring in as many foreign students as possible, the American students be damned, as long as those foreign students stay in the US after their training? Humans live long enough that education acquisitions approximate a zero sum game, so better to deprive the world, no?
