That's really the key problem facing US universities, from land-grant colleges to the Ivies: everyone depends at least in part on closing budgetary gaps with global students who pay full freight. Current Administration policies, both specifically targeted at foreign students and more generally at higher education and immigration, are poisoning the seed corn colleges and universities rely on. The only good news, relatively speaking, is that Europe is evidently constitutionally incapable of taking advantage of what is a genuinely one-in-an-imperial-lifetime chance to drain intellectual capital from the United States, which means that America and our higher education system can recover from this, should we have the fortitude to do so in the future -- there just isn't much in the way of competition.
