Damn you Matt, you scooped my "Migration and Development" post, and even got some climate change in. I love it though. Compensate poor countries for Western carbon emissions by letting their citizens move there.
Anyway, my post was going to be that Lant Pritchett is (was) in Juba today (yesterday) to give a talk about Growth Strategies. Which was good and will probably help shape the Growth Strategy for Southern Sudan. But it was also a grim reminder of the limits of growth. Ten years of insane Chinese-style growth will probably take Southern Sudan to Kenya's level of income. Ten years of ridiculously optimistic growth.
How about a development intervention which can take a Sudanese citizen's income to US levels overnight?
The potential gains to poor people of being allowed the opportunity to work in a rich country for even a few weeks blow every other conceivable anti-poverty measure completely out of the water.
The picture up top comes from this presentation.
