One of the great drivers of the alienation that has made Donald Trump possible is that the growth in the American economy has been weak. In the decade from 2005 to 2015, there was not one year when the US hit three per cent growth. And to the extent there's been growth, virtually all of it has been collected by the top 10 per cent of the population. Obviously, if we knew how to make growth faster, we would. We don't. And it's very difficult to make growth more broadly shared. Because it's not just the US that has this problem.

One of the things that always drives any practitioner of journalism crazy is you'll run it people who say why doesn't the media cover this or that? Well of course the media covered it.

The Great Society went wrong for three major reasons. First, the self-organization the Johnson administration promoted turned out to be not the pooling of family and community resources into shops and businesses, but political pressure for government handouts. Second, the Great Society failed to anticipate the perverse side-effects of handing money out to people who have done nothing to earn it. Third, while the Great Society was showering money on the poor, the Supreme Court was with childlike glee smashing to bits traditional methods of maintaining law and order.

I think the single most important question is how do you maximize the number of children who grow up in stable two-parent households. We know in all kinds of ways it makes a huge difference to how kids come out and we are hardening into a caste society where some kids do better in all kinds of ways because they have two parents and others don't.

[In politics,] when there is no reason to speak, there is a reason not to speak.

If you go on TV and say there's no other country in the world where you can be born poor and become rich, you get a huge megaphone. If you tell the truth, which is that most of the studies show actually the United States is worse than anybody except Britain in upward mobility, there is no audience for you.
