I can't help linking two things I came to notice lately:
1) Following the US elections in some detail over the last few days, I couldn't help but notice the venom against those who do well academically. Words like 'elitist', 'egghead' etc....with meanings that would have positive connotations in the rest of the world appear to have become profanities in American discourse. I don't know how representative political blogs are of American public opinion in general.
Compare and contrast with the culture in other up-and-coming economic powers like India and China.
2) The influx of American 'brains' here. Most Western expats used to be European - particularly British. But now Americans are really making their presence felt. They're everywhere.
Of course, this could simply be because of the economic boom in the Gulf caused by rising fuel prices among other things.
But maybe it is also linked to the first factor? More American eggheads are leaving because they don't feel appreciated at home? That is certainly the reason why educated Arabs leave the Middle East. So is the brain drain now beginning to reverse?
