Donald Trump’s astonishing victory in the United States presidential election has made one thing abundantly clear: too many Americans – particularly white male Americans – feel left behind.

It is not just a feeling; many Americans really have been left behind. It can be seen in the data no less clearly than in their anger. And, as I have argued repeatedly, an economic system that doesn't "deliver" for large parts of the population is a failed economic system. So what should President-elect Trump do about it?
