To the untrained observer Davos man and Davos woman might look the same as ever: well-fitting clothes, mobile phone clamped to ear, iPad affixed to finger, a confident "master-of-the-universe" gleam in the eye.
But something has changed in the World Economic Forum delegates this year. A powerful sense of social responsibility has been kindled in their hearts. The message of the global Occupy protesters, and all those jibes about the wealth of the "1 per cent" have not, contrary to popular assumption, been unnoticed.
Capitalism is about successful adaptation, and these delegates have adapted to the new environment. Two themes have run through the first two days of this year's summit: frugality and philanthropy.
First the frugality. Happily, the British have been world leaders in this area. To bang the drum for the London Olympics, the Diamond Jubilee and the ailing UK economy, the British delegation held a tea party. The event was described by the mayor's office as "frugal and efficient". But it did have British model Lily Cole there to add some glamour.
And it's not just Governments that are attuned to the need to cut out the excess at a time when global unemployment is heaped as high as this year's record snowfall in Davos.
