I’m all for it, but I’m wondering if the rhetoric surrounding the idea is entirely helpful. Reading this article on the collapse of the trade talks in Cancun, you’d get the impression that if rich countries were only more generous, they would lower their tariff barriers to products from poor countries. But generosity isn’t the question. These taxes punish rich countries’ consumers, too. Their governments don’t need to be more generous, just smarter–and bolder in taking on special interests.
