Give credit where credit is due: Nouriel Roubini of New York University’s Stern School of Business was right. On February 20 2008, I wrote a column entitled “America’s economy risks the mother of all meltdowns”, based on his analysis of the 12 steps to disaster. Alas, not only has the US taken those steps, but it has also – with help from others, including the UK – dragged the world behind it.
