The annual meeting of the World Economic Forum kicks off in Davos next week, replete with captains of industry and world leaders. The FT's US managing editor Gillian Tett and Fusion's senior editor Felix Salmon join host Cardiff Garcia to debate the merits of the gathering of the rich and powerful in the Swiss Alps. They also discuss the theme of privacy in an age of enhanced security measures and new technology. Finally, with the workforces of several developed countries expected to shrink in the near future, Alphaville's Matt Klein dissects the economics of ageing populations.
