Not all roads lead to London

Megan notes that there are now more than three million Britons living abroad and argues:

I assume this has something to do with the fact that it is very easy for Britons to go to wealthy, English-speaking countries, and also that there’s a relative lack of migration opportunities in Britain. If you’re American or Australian, you can always pick up and try another city, but in Britain, you mostly move to London or you . . . move to London. This is an exaggeration, of course, but there’s nothing like the ability to say, “You know what, things aren’t going so well in Boston, so I’m moving to LA.” If the economy, or the job opportunities are bad in London, they’re probably bad everywhere else in the UK too. Naturally there’s also the fact that Britain’s a crowded island where things are very expensive; an engineer can instantly boost his standard of living quite a bit by moving this side of the pond.
