Mitt Romney is leaning forward in his chair, his eyes flashing, his voice sharp.

It’s a strange look for the 72-year-old senator, who typically affects a measured, somber tone when discussing Donald Trump’s various moral deficiencies. But after weeks of escalating combat with the president—over Ukraine, and China, and Syria, and impeachment—the gentleman from Utah suddenly appears ready to unload.

What set him off was my recitation of an argument I’ve heard some Republicans deploy lately to excuse Trump’s behavior. Electing a president, the argument goes, is like hiring a plumber—you don’t care about his character, you just want him to get the job done. Sitting in his Senate office, Romney is indignant. “Are you worried that your plumber overcharges you?” he asks. “Are you worried that the plumber’s going to scream at your kids? Are you worried that the plumber is going to squeal out of your driveway?” I am playing devil’s advocate; he is attempting an exorcism.

Where in the pantheon of American commercial titans does Jeffrey Bezos belong? Andrew Carnegie’s hearths forged the steel that became the skeleton of the railroad and the city. John D. Rockefeller refined 90 percent of American oil, which supplied the pre-electric nation with light. Bill Gates created a program that was considered a prerequisite for turning on a computer.

At 55, Bezos has never dominated a major market as thoroughly as any of these forebears, and while he is presently the richest man on the planet, he has less wealth than Gates did at his zenith. Yet Rockefeller largely contented himself with oil wells, pump stations, and railcars; Gates’s fortune depended on an operating system. The scope of the empire the founder and CEO of Amazon has built is wider. Indeed, it is without precedent in the long history of American capitalism.

DUBLIN—Few people were talking about Irish reunification in the spring of 2016: Most assumed that the Good Friday Agreement had put the issue on ice for the foreseeable future. Northern Ireland’s mainly Protestant pro-British majority and the Catholic minority, which traditionally favored reuniting with the Republic of Ireland, had been living in peace after decades of sectarian violence. Where was the urgent need for such a drastic change?

Then the unforeseen happened. The United Kingdom voted narrowly to leave the European Union. Suddenly, Northern Ireland—which as part of the U.K. had voted to remain in the EU—was to be taken out of the bloc; the border between Northern Ireland and the Republic of Ireland, an EU member state, would once again be a tangible barrier to movement and trade after a protracted period of near-invisibility. Warnings proliferated of the consequences—economic, security, political—of separating the two sides of the island of Ireland. Chief among these was the risk that the border would again be a flashpoint for conflict, a resumption of the Troubles, which killed more than 3,500 people over 30 years.

The British people have changed their mind about Brexit. Beginning in the summer of 2017, and accelerating in the summer of 2018 by an ever wider margin, British people have told pollsters that they voted wrong in the Brexit referendum of June 2016.

Over that same period, however, Britain’s Conservative Party has become more and more committed to Brexit. Sixty-three percent of Conservative Party supporters would rather see Scotland secede from the United Kingdom than abandon the Brexit project. Sixty-one percent of Conservatives would accept significant damage to the British economy to achieve Brexit. Fifty-nine percent would let Northern Ireland go. Fifty-four percent would rather see the Conservative Party itself destroyed than yield on Brexit.

Several weeks ago, I met up with a friend in New York who suggested we grab a bite at a Scottish bar in the West Village. He had booked the table through something called Seated, a restaurant app that pays users who make reservations on the platform. We ordered two cocktails each, along with some food. And in exchange for the hard labor of drinking whiskey, the app awarded us $30 in credits redeemable at a variety of retailers.

I am never offended by freebies. But this arrangement seemed almost obscenely generous. To throw cash at people every time they walk into a restaurant does not sound like a business. It sounds like a plot to lose money as fast as possible—or to provide New Yorkers, who are constantly dining out, with a kind of minimum basic income.

It is easy to look at today’s crop of sinking IPOs—like Uber, Lyft, and Peloton—or scuttled public offerings, like WeWork, and see an eerie resemblance to the dot-com bubble that popped in 2000.

• Both then and now, consumer-tech companies spent lavishly on advertising and struggled to find a path to profit.

• Both then and now, companies that bragged about their ability to change the world admitted suddenly that they were running out of money.

• Both then and now, the valuations of once-heralded tech enterprises were halved in a matter of weeks.

• Both then and now, there was a widespread sense of euphoria curdling into soberness, washed down with the realization that thousands of workers in once-promising firms were poised to lose their jobs.

Nessa Coyle calls it “the existential slap”—that moment when a dying person first comprehends, on a gut level, that death is close. For many, the realization comes suddenly: “The usual habit of allowing thoughts of death to remain in the background is now impossible,” Coyle, a nurse and palliative-care pioneer, has written. “Death can no longer be denied.”

I don’t know exactly when my mother, who eventually died of metastatic breast cancer, encountered her existential crisis. But I have a guess: My parents waited a day after her initial diagnosis before calling my brother, my sister, and me. They reached me first. My father is not a terribly calm man, but he said, very calmly, something to this effect: “Your mother has been diagnosed with breast cancer.”

Just under a century ago, the Soviet Union embarked on one of the strangest attempts to reshape the common calendar that has ever been undertaken. As Joseph Stalin raced to turn an agricultural backwater into an industrialized nation, his government downsized the week from seven to five days. Saturday and Sunday were abolished.

In place of the weekend, a new system of respite was introduced in 1929. The government divided workers into five groups, and assigned each to a different day off. On any given day, four-fifths of the proletariat would show up to their factories and work while the other fifth rested. Each laborer received a colored slip of paper—yellow, orange, red, purple, or green—that signified his or her group. The staggered schedule was known as nepreryvka, or the “continuous workweek,” since production never stopped.

The idea that there are five distinct “love languages” may be as familiar to some people today as the idea that there are seven continents, four seasons, or three Stooges—which is a pretty spectacular showing, all told, for a concept that was introduced in a 1992 book by a Southern Baptist pastor that was aimed mostly at married Christian couples. The author, Gary Chapman, based his theory that everyone has a primary love language (that is, a category of behaviors that they most immediately associate with affection) on his own observations as a counselor. Enumerated in the book and now well known to millions, the five love languages are quality time, physical touch, acts of service, giving and receiving gifts, and words of affirmation.

What was Hillary Clinton thinking? The 2016 Democratic nominee, for some reason, felt the need to insert herself into the 2020 race with an attack on Tulsi Gabbard, an oddball Democratic presidential contender who barely registered in polls. The congresswoman from Hawaii is a completely discreditable candidate—more on that in a moment—but Clinton’s accusation that Gabbard is a tool of the Russians was so blunt and clumsy that it has added new life to a primary bid that should never have existed in the first place. Within a day, Gabbard was already fundraising off of it, a development as predictable as a sunrise.

Clinton fired at Gabbard in a recent podcast, during which she made reference to an unnamed Democrat who Clinton believed was readying a third-party challenge. “I’m not making any predictions,” Clinton said, “but I think [the Russians] have got their eye on someone who’s currently in the Democratic primary and are grooming her to be the third-party candidate. She’s the favorite of the Russians. They have a bunch of sites and bots and other ways of supporting her so far.”
