We focus on that really repulsive minority of racists. But then there's a continuum that goes all the way to, you know, what used to be called the white backlash or to, you know, the feelings of some white people that they're losing out and that the jobs and power and sort of the culture is drifting away from them and toward people who don't look like them, who don't - who they don't know very well. And that's not necessarily - I don't equate that with the hardcore ideological hatred of self-identified racists.

The biggest issue for me is whether large numbers of Americans can begin to think that government can actually help make the country a fairer place. And that's partly a matter of policies that achieve results in terms of reducing inequality and raising middle-class and working-class incomes, which have been flat for decades. But it's also symbolic and rhetorical, it's whether Hillary Clinton can - or whoever's president - can persuade Americans that it's happening and that they can begin to trust their elected officials a little bit more and their institutions of government a little bit more.

The ranks of educated professional swelled as more Americans went to college and more Americans sort of adopted a more cosmopolitan lifestyle and worldview. And as the Democrats were looking for an alternative to the unions who no longer seemed like a large enough base for the party, they found the educated who veered more toward a progressive cultural outlook, who may have had - may have been working in the financial sector, in entertainment, in media, in universities. That became really the rank and file of the Democratic Party over a long period of time.

I've read a lot of war writing, even World War I writing, the British war poetry of Wilfred Owen and Siegfried Sassoon, Robert Graves's memoir "Goodbye to All That," and a civilian memoir "Testament of Youth" by Vera Brittain .

Since I was a kid. I had this series by Ballantine Books about the history of World Wars I and II. In my 20s, it was the Vietnam War literature of novelists like Tim O'Brien, Philip Caputo, and Tobias Wolff, and then nonfiction such as "A Bright Shining Lie" by Neil Sheehan and "The Best and Brightest" by David Halberstam . Those are the two best histories of Vietnam.

Inequality provokes a generalized anger that finds targets where it can--immigrants, foreign countries, American elites, government in all forms--and it rewards demagogues while discrediting reformers.

This is why mustard gas is such a danger or any weapon of mass destruction is such a dangerous thing because it - it's victims become everyone in the end.
