So what??? Maybe the schools could lower their prices for US Citizen students and spend a little of their enormous endowments? Maybe the professors could take a pay & benefits cut? Maybe they could fire many of the extremely worthless “administrators”? Maybe they could stop funding DEI and other WOKE BS administrators and programs? Maybe?
The real problem is not actually the universities with massive endowments. They have spies and fake students, but the big issue is with universities that are doing major research and have only moderate or low endowments. Those are the ones that are deeper into the desperation of "let's milk foreign students". Those are the ones who have research worth stealing but who lack resources to prevent corporate espionage and an ability to protect their secrets against foreign appropriation.
Without foreign students paying full out of state tuition, I expect all American students will pay higher tuition.
