It used to be that the working class, broadly speaking - Americans who worked with their hands, who worked in factories, who were not in management - were an interest group, a political interest group. And their main spokespersons were the Democrats. Their platform was the Democratic Party. And that began to change after the 1960s. Not for black or other working class Americans, but for white working class.

In a sense, whites who were always sort of the unthinking majority who didn't think of themselves necessarily as one among many interest groups but is simply the dominant group, now as whites become - are close to becoming a minority of Americans, are becoming a political interest group. And that's what Donald Trump is playing to. And it's a really dangerous, volatile game.

Like an odorless gas, [inequality] pervades every corner of the United States and saps the strength of the country's democracy. But it seems impossible to find the source and shut it off.

Inequality hardens society into a class system. Inequality divides us from one another... Inequality undermines democracy.

When Donald Trump yells at his supporters to throw somebody out of the hall - and usually that somebody is brown or black or often is - that means he's galvanizing a kind of mob spirit, which is also a racial mob spirit.

The literature of the Spanish Civil War is also important to me. Above all George Orwell's "Homage to Catalonia" as well as the writing of John Dos Passos and Ernest Hemingway. They worked on a film together in Spain during that war, which ended their friendship.

At the heart of the matter is a battle between wish and fear. Fear generally proves stronger than a wish, but it leaves a taste of disappointment on the tongue.
