This is worrisome but not that much. Labour movement is fine as long as the reverse also happens. If you lose a doctor to New Zealand but can gain a doctor from Argentina, then assuming that the skills are fungible and a commodity, that should be fine. And at that high level of analysis, it is. I quote:
Britain is experiencing the worst "brain drain" of any country as highly qualified professionals settle abroad, an authoritative international study showed yesterday.
There are now 3.247 million British-born people living abroad, of whom more than 1.1 million are highly-skilled university graduates, say the researchers.
No other nation is losing so many qualified people, it points out. Britain has now lost more than one in 10 of its most skilled citizens, while overall only Mexico has had more people emigrate.
Prof David Coleman, of St John's, Oxford, said the brain drain was "to do with quality of life, laws and bureaucracy, tax and all the rest of it".
All this to be taken with a grain of piquant salt!!!
