There's no such thing as race
(but religion), and I certainly don't see what Northwest Europeans have got in common with slovenly mediterraneans or violent eastern europeans.
The reason why SA imports so much is arguably because most academics from there are glad to get out and do some interesting work abroad...
(but don't most of them come back ?)generally going abroad from whatever country you come from makes you feel good and seem more interesting to other people (on a superficial level), alas, not so many academics are tempted to go there, due to the lack of appeal of the culture, so you end up with agglomerations of academics in hotspot areas where funding follows, and the contrast grows. I suppose if the west does start taking an economic dive, these less culturally attractive places, may decide to set up little science city enclaves where academic expats can earn a lot more and be shielded from the locals and their hateful customs
(Silicon Valley did not hurt Europe as most expected); but somehow, I doubt it will be enough to catch up.
The more interesting question, is whether they can stop the brain drain, and find ways to keep their best people... and to clean up the corruption
(corruption and islam...) in their universities... again... where's the incentive for them? They're trying to develop luxury tourism, but they look down on the culture of their customers... how can Arab countries (apart from Egypt) seriously compete with the charms of laid back fun and easy pussy in so many parts of latin america and eastern asia?
