President Trump watches a lot of television. I mean, really a lot. His favourite channel is Fox. Now just imagine somebody wants put a message in front of the president. You can hire a lobbyist or you can buy a minute on Fox or you can even pay somebody at a think tank to articulate your message and then pay a booker at that think tank to get that person on Fox and put the thought directly in the president's ear.

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.

I keep telling my American friends, "If you think of Donald Trump as only something that is happening inside the United States, you're missing it." Because there are Trump-like events happening across the Western world, in Warsaw Pact countries, in France, Germany, Austria, the Netherlands. As we speak, the second-largest party in the Dutch legislature - who's more level-headed than the Dutch? - is Geert Wilders's party, which is a very Trump-like party, and they've got 33 out of 150 seats.

I have a range of scenarios. One of them is a chaos, that what could happen is Congress does step up a little bit and the administration is paralyzed. And we go through all kinds of constitutional crises, impeachment or the 25th Amendment removal process. Another frightening scenario is Donald Trump is steering his way to a series of international confrontations at the same time as he's appeasing Russia.

Donald Trump, as a businessman, he's not much of a builder and he's not much of dealmaker and he certainly isn't very good at making expenses line up with income. But he is a marketing genius. He must have seen an empty market niche that no one but him filled.

One of the reasons I've been interested in the US health care is that here is something you can do, that could lift one of the largest burdens of worry from the shoulders of tens of millions of people for whom the rest of the economy isn't working. A lot of the things that are in Obamacare that Republicans don't like were deliberately put there to force Republicans to negotiate. Republicans wouldn't negotiate, so we got Obamacare with all of the fur on it. Once it's there, of course, it's very hard to take health care benefits away from people, as the Republicans discovered.

We're not free because other people are nice, maybe other people aren't nice that day. We're free because we expect the institutions of government to work impersonally. That we expect people in government to understand they don't work for the president or the prime minister, they work for the government. And the government is always there.
