...what should be done? Some would argue: nothing at all. The view is widely held, particularly in the US, that the world needs a big purge of past excesses. Recessions, on this line of argument, are good. People who hold this view also argue that governments caused all the mistakes. The market would, they insist, be incapable of the errors we have seen. To them, Alan Greenspan’s confession last week that “I made a mistake in presuming that the self-interest of organisations, specifically banks and others, was such that they were best capable of protecting their own shareholders” was about as welcome as Brutus’s knife was to Caesar.
Yet the idea that a quick recession would purge the world of past excesses is ludicrous. The danger is [that] a mountain of private debt – in the US, equal to three times GDP – topples over into mass bankruptcy. The downward spiral would begin with further decay of financial systems and proceed via pervasive mistrust, the vanishing of credit, closure of vast numbers of businesses, soaring unemployment, tumbling commodity prices, cascading declines in asset prices and soaring repossessions. Globalisation would spread the catastrophe everywhere.
Many of the victims would be innocent of past excesses, while many of the most guilty would retain their ill-gotten gains. This would be a recipe not for a revival of 19th-century laisser faire, but for xenophobia, nationalism and revolution. As it is, such outcomes are conceivable. Choosing to risk such an outcome would be like deciding to let a city burn in order to punish someone who smoked in bed. Risking huge damage now in the hope of lowering moral hazard later is mad.
