It's a fairly common symptom of a financial crisis, and putting your family up in a new country and loading up on assets there is one of the more outwardly visible symptoms of it. (Again, see Japan's history–the data's in the OP's article.)
China's zero-unemployment policy have created some incredibly unsustainable trends, and they know it. Meanwhile, Beijing has to figure out how it's going to keep a nation that would span about five time zones unified, when they have a wealth disparity like the world's never known.
India, meanwhile, is destined to remain incredibly capital poor, despite being able to feed itself pretty handily. If you're a wealthy Indian elite, you're capital rich but constrained by your local geography.
Combine in the negative-interest-rate policies many countries have adopted, and the money's absolutely going to migrate away from that (as low as rates are elsewhere, they're still higher).
Anyway, I don't think wealthy Chinese nationals are limiting themselves to buying a condo in Champaign, IL. But when you expatriate large amounts of currency, winding up with a house and a few supercars in the destination country isn't a rare phenomenon.
And yeah, the colleges are good, too, but they were also good when we had comparatively few Chinese students attending them, too.
