From Tim Worstall at the Adam Smith Institute:
That is the annual change in child mortality in those selected countries. No country, no group of countries, has ever seen anything like this, it simply has not happened so quickly anywhere else at all. Something, blessedly, is going very right indeed in this world. My suggestion is that we keep doing exactly what it is that we are currently doing: we might call it globalisation, foreign direct investment, openness to trade or as Madsen puts it, buying things made by poor people in poor countries. But it’s working, isn’t it?
