Yesterday, President Donald Trump canceled a meeting with the new Danish prime minister, Mette Frederiksen, because she refuses to discuss the sale of Greenland. Greenland used to be a Danish colony but now belongs to the people of Greenland—the Danish government could not sell the island even if it wanted to. Trump likely did not know that Denmark is one of America’s most reliable allies. Danish troops, for example, fought alongside U.S. forces in Iraq and Afghanistan and suffered 50 fatalities, and Danish forces were among the earliest to join the fight against the Islamic State.

Many Americans may laugh off Trump’s latest outrage, but Trump crossed an important line. It is one thing to float a cockamamie idea that no one believes is serious or will go anywhere. “Let’s buy Greenland!” Yes, very funny. A good distraction from the economy, the failure to deal with white supremacy, White House staff problems, or whatever is the news of the day. It is quite another to use leverage and impose costs on Denmark in pursuit of that goal—and make no mistake, canceling a presidential visit is using leverage and imposing costs. What’s next, refusing to exempt Denmark from various tariffs because it won’t discuss Greenland? Musing on Twitter that America’s defense commitments to Denmark are conditional on the negotiation? Intellectual justifications from Trump-friendly publications, citing previous purchase proposals and noting Greenland’s strategic value and abundance of natural resources? (That last one has already happened.)

In the summer of 1987, I graduated from a public high school in Austin, Texas, and headed northeast to attend Yale. I then spent nearly 15 years studying at various universities—the London School of Economics, the University of Oxford, Harvard, and finally Yale Law School—picking up a string of degrees along the way. Today, I teach at Yale Law, where my students unnervingly resemble my younger self: They are, overwhelmingly, products of professional parents and high-class universities. I pass on to them the advantages that my own teachers bestowed on me. They, and I, owe our prosperity and our caste to meritocracy.

Two decades ago, when I started writing about economic inequality, meritocracy seemed more likely a cure than a cause. Meritocracy’s early advocates championed social mobility. In the 1960s, for instance, Yale President Kingman Brewster brought meritocratic admissions to the university with the express aim of breaking a hereditary elite. Alumni had long believed that their sons had a birthright to follow them to Yale; now prospective students would gain admission based on achievement rather than breeding. Meritocracy—for a time—replaced complacent insiders with talented and hardworking outsiders.

Every morning of my Joe Rogan experience began the same way Joe Rogan begins his: with the mushroom coffee.

It’s a pour-and-stir powder made from lion’s mane and chaga—“two rock-star mushrooms,” according to Joe—and it’s made by a company called Four Sigmatic, a regular advertiser on Joe Rogan’s wildly popular podcast. As a coffee lover, the mere existence of mushroom coffee offends me. (“I’ll have your most delicious thing, made from your least delicious things, please,” a friend said, scornfully.) But it tastes fine, and even better after another cup of actual coffee.

Next, I took several vitamin supplements from a company called Onnit, whose core philosophy is “total human optimization” and whose website sells all kinds of wicked-cool fitness gear—a Darth Vader kettlebell ($199.95); a 50-foot roll of two-and-a-half-inch-thick battle rope ($249.95); a 25-pound quad mace ($147.95), which according to one fitness-equipment site is a weapon dating back to 11th-century Persia. I stuck to the health products, though, because you know how it goes—you buy one quad mace and soon your apartment is filled with them. I stirred a packet of Onnit Gut Health powder into my mushroom coffee, then downed an enormous pair of Alpha Brain pills, filled with nootropics to help with “memory and focus.”

In 1989, When Harry Met Sally posed a question that other pop-cultural entities have been trying to answer ever since: Can straight men and women really be close friends without their partnership turning into something else? (According to The Office, no. According to Lost in Translation, yes. According to Friends … well, sometimes no and sometimes yes.) Screenwriters have been preoccupied with this question for a long time, and according to a new study published in the Journal of Relationships Research, the question is also likely to be on the minds of people whose romantic partners have best friends of the opposite sex.

For the study, Eletra Gilchrist-Petty, an associate professor of communication arts at the University of Alabama in Huntsville, and Lance Kyle Bennett, a doctoral-degree student at the University of Iowa, recruited 346 people, ranging in age from 18 to 64, who were or had been in a heterosexual relationship with someone who had a different-sex best friend. When they surveyed participants’ attitudes toward cross-sex best friendships, they found that people who are engaged to be married look more negatively on those friendships than married, single, or dating people. They also found that people who are skeptical of cross-sex best friendships in general are more likely to “lash out” at their partner when they feel threatened by the partner’s best friend—as opposed to constructively communicating with their partner, or with the friend, about the situation.

In an age of persistently high inequality, work in high-cost metros catering to the whims of the wealthy—grooming them, stretching them, feeding them, driving them—has become one of the fastest-growing industries.

The MIT economist David Autor calls it “wealth work.”

Low-skill, low-pay, and disproportionately done by women, these jobs congregate near dense urban labor markets, multiplying in neighborhoods with soaring disposable income. Between 2010 and 2017, the number of manicurists and pedicurists doubled, while the number of fitness trainers and skincare specialists grew at least twice as fast as the overall labor force.

While there are reasons to be optimistic about this trend, there is also something queasy about the emergence of a new underclass of urban servants.

No one set out to turn the airwaves into a political weapon—much less deputize talk-radio hosts as the ideological enforcers of a major American political party. Instead the story of how the GOP establishment lost its power over the Republican message—and eventually the party itself—begins with frantic AM radio executives and a former Top 40 disc jockey, Rush Limbaugh.

In the late 1980s, AM radio was desperate for new content. Listeners had migrated to FM because music sounded better on there, and advertising dollars had followed. Talk-radio formats offered a lifeline—unique programming that FM didn’t have. And on August 1, 1988, Limbaugh debuted nationally. At the outset, Limbaugh wasn’t angling to become a political force—he was there to entertain and make money. Limbaugh’s show departed from the staid, largely nonpartisan, interview and caller-based programs that were the norm in earlier talk radio. Instead, Limbaugh was a consummate showman who excited listeners by being zany and fun and obliterating boundaries, offering up something the likes of which many Americans had never heard before.

The strange little PowerPoint asks me to imagine being the new kid at school. I feel nervous and excluded, its instructions tell me. Kids pick on me. Sometimes I think I’ll never make friends. Then the voice of a young, male narrator cuts in. “By acting differently, you can actually build new connections between neurons in your brain,” the voice reassures me. “People aren’t stuck being shy, sad, or left out.”

The activity, called Project Personality, is a brief digital activity meant to build a feeling of control over anxiety in 12-to-15-year-olds. Consisting of a series of stories, writing exercises, and brief explainers about neuroscience, it was created by Jessica Schleider, an assistant professor at Stony Brook University, where she directs the Lab for Scalable Mental Health. She sent it to me so I could see how teens might use it to essentially perform psychotherapy on themselves, without the aid of a therapist.

In a kinder world, archaeologists would study only formal cemeteries, carefully planned and undisturbed. No landslides would have scattered the remains. No passersby would have taken them home as souvenirs, or stacked them into cairns, or made off with the best of the artifacts. And all this certainly wouldn’t be happening far from any evidence of human habitation, under the surface of a frozen glacial lake.

But such an ideal burial ground wouldn’t have the eerie appeal of Skeleton Lake in Uttarakhand, India, where researchers suspect the bones of as many as 500 people lie. The lake, which is formally known as Roopkund, is miles above sea level in the Himalayas and sits along the route of the Nanda Devi Raj Jat, a famous festival and pilgrimage. Bones are scattered throughout the site: Not a single skeleton found so far is intact.

For a handful of Democratic candidates stuck at 1 percent (or lower) in the polls, a Wednesday afternoon in the dog days of August could be the moment when their lifelong dream of the presidency dies a quiet death.

August 28 is the deadline for candidates to meet the Democratic National Committee’s heightened threshold for entry into the September debate, and as much as half the field is expected to wind up on the sidelines. Those who don’t make the cut will, at a minimum, be forced to reassess the viability of their long-shot bids. Some of those also-rans may trudge on through the fall, in the hopes of rebounding for the next debate in October, or simply out of a commitment to stay in the race until the first votes are cast in Iowa next February.

I. Wiped Out

“You ever chop before?” Willena Scott-White was testing me. I sat with her in the cab of a Chevy Silverado pickup truck, swatting at the squadrons of giant, fluttering mosquitoes that had invaded the interior the last time she opened a window. I was spending the day with her family as they worked their fields just outside Ruleville, in Mississippi’s Leflore County. With her weathered brown hands, Scott-White gave me a pork sandwich wrapped in a grease-stained paper towel. I slapped my leg. Mosquitoes can bite through denim, it turns out.

Cotton sowed with planters must be chopped—thinned and weeded manually with hoes—to produce orderly rows of fluffy bolls. The work is backbreaking, and the people who do it maintain that no other job on Earth is quite as demanding.
