Stephan:   The growing inequity of wealth in the world has become so extreme that long term structural changes are occurring in the world. As Bank of England chief economist Andrew Haldane explains, "There is rising evidence that extreme inequality harms, durably and significantly, the stability of the financial system and growth in the economy. It slows development of the human, social and physical capital necessary for raising living standards and improving well-being.” And yet there was hardly a word about any of this in the mid-term campaigns that are now coming to an end. Why is this happening do you think? I think it is because the uber-rich are just buying politicians like hiring plumbers. This is an inherently unstable situation because when people no longer believe in their government as a source of help and protection they will start looking for something else.
