The AFR today (now yesterday) reprinted A DOOR THAT WILL NOT CLOSE from Foreign Affairs A neat little piece that suggests that the issue of migration needs to be thought of differently - in terms of not how you attempt to stop it or control it but on how you make the flows work for all concerned. I particularly like the idea of returning tax revenues from a host country back to a citizens country of origin so that everyone wins. Linked to the other kinds of developments that you might want to see occur in other countries (rule of law, property rights, etc) this could be quite a pro-development move.
