Do the delegates in Davos understand 'fairness'?

There is an urgent and gloomy tone to this year's gathering of the world's richest and most powerful people at the world economic forum in Davos.

More than 2,600 delegates come with fresh warnings ringing in their ears that the global economy as we know it is in danger.

At his State of the Union address in America on Tuesday President Obama called for a "fairer America" where the rich carry what he called a "fair" share of the burden.

The BBC asked Daniel Gross, the Economics Editor at Yahoo! Finance if delegates at Davos understand the notion of "fairness".
