The man who made it OK to talk about immigration
It takes a lot to make the subject of immigration respectable for liberals, at least if you’re pointing out its problematic aspects. But Paul Collier, an Oxford economist specialising in the world’s bottom billion, has, in the 270-odd pages of his new book Exodus, opened up the issue for the left — well, for all comers, actually. Which, for a book suggesting among other things that, left to itself, there is no natural limit to immigration, is quite something.
