Oooh .... "you and the likes of you", eh ? I'll let the others speak for themselves, but "me and the likes of me" are  not "thronging" for a visa to the US and certainly not to settle there. Did the "likes of you" ever "throng" for one and hence the presumption maybe ?

Face it, America is less and less the top destination for the cream of the crop immigrants. More and more educated and higly-skilled people from countries like India, China and elsewhere dont feel they need to come to America to realize their potential. There's plenty going on in their own neighborhood to keep them occupied and satisfied.
