Roubini on mega-threats for the world economy

Nouriel Roubini - aka Dr Doom - has never knowingly been overly optimistic; at least he's consistent here, arguing that the super-elite at Davos seem to be blind to the extent of the mega-threats facing the global economy.

He thinks that we are "facing not only the worst of the 1970s (repeated negative aggregate supply shocks), but also the worst of the 2007-08 period (dangerously high debt ratios) and the worst of the 1930s, with the rollback of globalisation and the threats that this poses to international stability.

Is he right? You might argue that he only has to be right once...
