How to get rich

Many poor people became richer by leaving their country of birth. [Lant Pritchett and Michael Clemens] estimate that "two of every five living Mexicans who have escaped poverty did so by leaving Mexico; for Haitians it is four out of five." There is a point to this exercise: Clemens and Pritchett want to call attention to the fact that migration has made a lot of migrants richer.
