As it always does this time of year, my inbox is filling up with messages of a certain kind. They all begin with: "I'm here in Davos" and then, in an intellectual form of name dropping, proceed to mention key words and phrases such as Geopolitical Risk, G-Zero World, and Rise of Regions. This, of course, sounds really heavyweight and important. But I am not fooled. Nobody knows what those words mean. The only purpose is inform me that the sender is among the elect glitterati who get invited to the World Economic Forum's annual meeting in Davos.
