A generation ago, or two, when there were three channels, plus PBS, and when you needed - when you needed 15 million people to make a living, the media could focus on the broad country. And most people had no choice about getting political information. It was there at 6:30 whether you wanted it or not.

Americans are about to discover that their system is more vulnerable than they thought. There's a lot of complacency in American politics, there's a lot of complacency in advanced democracies generally.

World War II proved a hypothesis that Alexis de Tocqueville advanced a century before: the war-fighting potential of a democracy is at its greatest when war is most intense; at its weakest when war is most limited. This is a lesson with enduring relevance to our own times - and our own wars.

Maybe it's true that people with less extreme views who are also interested in public affairs have been driven out by a marketplace that doesn't offer them anything of the tone they want to listen to.

Democracy requires you to learn how to lose as well as how to exercise power when you win. And that requires restraint all around. One of the reasons it works is because when you win you don't do things that are so upsetting to the losers that they feel like they have less, they have more to gain by turning over the system.

Normally what happens in a new presidency is the president has a big agenda, and Congress is full of people with human weaknesses. And so the president indulges the human weaknesses of members of Congress in order to pass his agenda. This time it's the other way around. Donald Trump does not have much of an agenda. Congress burns with this intense Republican agenda and so does Congress that has to put up with the human weaknesses of the president in order to get a signature on the things it desperately wants to pass.

The big winners under the American fiscal system are the rich, who pay some of the lowest taxes anywhere in the world; the old, who are the main beneficiaries of the American social service state; farmers, rural people. These are Republican constituencies.
