there is a strong case to be made that the current crisis is in the strictest sense a crisis of globalisation, fostered and transmitted by the rapid and deep integration of very different economies. Fast-growing developing countries with underdeveloped financial systems were exporting savings to the developed world for packaging and re-export to them in the form of financial products.The global economy during the period of boom and savings glut had something in common with the old communist workers' joke: we pretend to work and they pretend to pay us.
