The UK features in the top ten both for migration in and emigration out. That is a telling fact, is it not?I think a detailed breakdown of those numbers would be interesting. A nation that steadily swaps newly-minted physicians and software engineers with imported cab drivers on a one-for-one basis is destined for trouble down the road.
(And before anybody can slap down the "That's racist!" card, I would note that yes, the cabby's kid may indeed become a physician or software engineer himself, which will do his homeland no good if he immediately lights out for better prospects elsewhere, to be replaced on the census rolls by yet another imported cab driver.)
