John Cassidy of the New Yorker has an interesting blog post about the annual gathering of the rich and powerful at the World Economic Forum in Davos, Switzerland. I hadn't realised that the delegates paid so much - tickets start at $71,000 - to attend. In Cassidy's opinion, 'The point of Davos is not to learn or think or do deals, but simply to be there - and to be seen to be there.'
