David Grossman with more stories which help explain the world of contemporary capitalism. He enters the strange world of high speed financial trading, where a millionth of a second can make the difference between fortune and failure. He learns about the increasing role of the financial sector, asking about the risks of our reliance on debt. Plus how South America tried to introduce its own brand of socialism and the growing influence and appeal of state-directed capitalism in places like China. Can free-market economies like Britain compete fairly?
