George Bush's thinly veiled accusation last week that Europe is perpetuating starvation in Africa by subsidising agricultural exports and by objecting to genetically modified food is both wrong and offensive. Africa is being starved of income and its people go hungry because the rich world spends little on aid and has done little to help the continent help itself by easing trade barriers. There is much talk about lifting Africa out of poverty, but not much in the way of action from either Brussels or Washington.
