Few humans, if any, are from where they find themselves at present. Most of them are from far, far away. This was true even of Africa before the exodus some fifty-thousand years ago, let alone of the continents subsequently inhabited. It is thus hardly surprising that migration is still continuing after the global economic crash (“Moving Out, On, and Back,” August 27, 2011). After all, it has always been essential for human survival, and especially in dire times. Perhaps the only surprise at this juncture is an increasingly inept handling of this primordial urge by sundry governments, as though it is of a recent and troubled vintage. As you argue, most migrants come and go depending on their economic fortunes in spite of all the impediments or enticements thrown their way by bungling governments. Therefore, it would make most sense to let migrants come and go exactly as they would wish. They are not fools, after all. As an added benefit of this simple but enlightened policy, the incoming and outgoing migrant numbers would be good gauges of economic fortunes of each country on their path.
