Then there are the high class FOBS. The KGS students going to Harvard and Yale, and the LUMS grads doing finance in Lehman brothers (although they are probably headed home now;) the movie makers and dress designers in NYC and the wanna be actors in LA also FOBS since they were born in South Asian countries.
Good post, but you are so wrong (as for the indication they are headed home)... Most of them are are already working elsewhere, with 'fatter' paychecks my friend!
