Earlier quoted context omitted.
Are you seriously saying that foreign students subsidize the education of US citizens? That is one of the most absurd statements I've ever read on HN. US student's educations are paid for by student loans, they fund their own tuitions I can assure you. Attending university in the US is a privilege and that does not mean you should be guaranteed a job in the United States upon graduation. You seem to have a real sense…
It may be a reference to the fact that many public colleges have tuition breaks for residents. The other side of that coin is availability. That practice gives those schools a financial incentive to grant full-retail foreign students admission priority over residents. That's certainly the case in California.
They increasingly admit more out of state and international students to deal with their increasing budget problems and to counteract otherwise necessary larger tuition increases.
I'm not saying this is good or bad. Just stating that this is happening.
