The world is wealthier than ever, but for whom? We are in Davos, where the world’s most powerful politicians and business leaders meet annually to discuss solutions to the world’s problems. Â鶹¹ÙÍøÊ×Ò³Èë¿Ú presenter Evan Davis will be joined by a high-level panel of decision-makers from the world of politics, business and banking – along with social activists and economists.

After the financial crisis of 2008, many people hoped a more equal world would emerge - that we might see a fresh start, reform of the banks, and a narrowing of the gap between rich and poor. But it has not quite gone to that plan. The richest 1% in the world, not only have lots of power, they still own nearly half the world’s wealth.

Evan Davis is joined in Davos by Christine Lagarde, from the International Monetary Fund, Mark Carney, Governor of the Bank of England, Sir Martin Sorrell, CEO of advertising giant WPP and Klaus Kleinfeld, CEO of Alcoa. Also joining are Robert J. Shiller, professor of Economics at Yale University and Winnie Byanyima, executive director at Oxfam International.
