Brilliant stuff. The work on remittances was a great "thin end of the wedge" to get the WB involved in migration but I agree it is time to move beyond considering migration only from the point of view of how much it benefits the place the migrant left. Measured by its impact on people migration is far, far, far and away the single biggest development intervention available. It is limited by rich country politics. Unfortunately in WB parlance those countries are called "shareholders."
