It was like a scene out of Le Carré: the brilliant agent comes in from the cold and, in hours of debriefing, empties his memory of horrors committed in the name of an ideology gone rotten. But this was a far bigger catch than some used-up Cold War spy. The former apparatchik was Joseph Stiglitz, ex-chief economist of the World Bank. The new world economic order was his theory come to life. He was in Washington for the big confab of the World Bank and International Monetary Fund. But instead of chairing meetings of ministers and central bankers, he was outside the police cordons. The World Bank fired Stiglitz two years ago. He was not allowed a quiet retirement: he was excommunicated purely for expressing mild dissent from globalisation World Bank-style.
