This is usually the time of year when politicians, big-shot bankers, and top diplomats converge on Davos, Switzerland for the annual World Economic Forum. But like last year, the event is expected to be far more downbeat than in years past when Angelina Jolie turned up to discuss global poverty and Naomi Campbell strutted around the Alpine village in very fashionable après-ski attire. This year the best attendees can look forward to is catching a glimpse of Chinese pianist Lang Lang or self-important director James Cameron. Depressing!
