American capitalism is in crisis - that's the view of Professor Luigi Zingales. He blames the links between big government and big business. For the man who cites Margaret Thatcher as his hero, his answer is more competition; more free markets; an end to subsidies and lobbying and less privilege for the few. That's the way he says that capitalism can "rediscover and renew its moral foundation". So can it really be the answer to tackling inequality and mending the American dream?
