I agree with Batya Ungar-Sargon’s observation that the main divide in the United States is not race, but economic class. I also agree with Jonathan Haidt’s observation that those who have lost touch can be identified by their lack of humor:

Intellectual life used to be fun,” Mr. Haidt said. “There’s an emergent community, from center left to center right, of people who feel politically homeless and are recognizing that the big division is no longer between left and right, but between people who are on the extremes, who are humorless and aggressive and deluded by their passion and tribalism, versus the middle 70 percent of the country.
