For most of the twentieth century, the US and the dollar reigned supreme. But economic power is shifting more and more away from the US to China and the other emerging economies. How much longer can the world’s biggest borrower be the leading political power? Filmed at the battle of ideas debate gets heated as speakers move from assessing the state of the US economy to suggesting what’s needed to fix it. Speakers include Professor Iwan Morgan, author and head of US Presidency Centre, Institute for the Study of the Americas, University of London; Phil Mullan, economist, author The Imaginary Time Bomb; Martin Wolf, author, associate editor and chief economics commentator, Financial Times.
