Terence, I believe that Serendipidy's point is that we here in the US have access to some of the best dancers in the world. I don't think that Serendipidy is guilty of any jingoistic crowing (I'm not even sure where Serendipidy lives).
I may point out, though, that the US has always imported more of its top level artists and scientists in all areas than it has developed domestically, a trend that has been maintained since our country's founding.
Doubtlessly, this fact is due to cynical American attitudes about education. That subject, however, is for another discussion board.
