"colleges were accepting way too many Asians"
Some of this is just kids being dumb, but some is Americans have a weird relationship with their Empire.
On one hand their parents and student loans are paying more money to fund the foreign exchange students and every foreign exchange student present is quite literally one local taxpayer who isn't getting an education yet is somehow supposed to pay for the system without an educated-level job. Even if the school accepts everyone, that just means the local taxpayers are on the hook for capex to make huge buildings that wouldn't be necessary without the demands of the Empire.
That sounds like a horrific deal for the local taxpayer, and it is, but Empires always suck at some level or another for pretty much everyone involved. However from a foreign aid and propaganda perspective that money is well spent, who else gets to propagandize the entire world's youth for practically no cost compared to military expenses? Its a lot cheaper to indoctrinate the world's kids at an American school than to wave expensive F-35 fighters at them in a threatening manner a decade later. In typical American corruption we officially spend like 0.1% of our federal budget on foreign aid and then bury things like state Uni budgets in the individual state budgets to pretend our Empire spends roughly nothing on foreign aid, but we really do spend lots of money on the Empire, for which we're theoretically running a profit, or if not "we" at least someone is running a profit.
I'd estimate the total cost to the GDP of empire has got to be something like 5% but its cheaper than the alternative, or so the people getting rich off the empire insist.
At any rate, my point is some of it is just kids being dumb, yet some of it is knowing for federal level foreign policy reasons their old high school buddy named XYZ can't go to college with them, despite his having to pay for it in taxes, because a foreigner is there in his place and supposedly everyone is better off for it, yet fundamentally on a personal level they still miss their old high school buddy XYZ.
