A 90-second failure of Newark Airport’s air-traffic safety systems, which blacked out communication to planes carrying thousands of passengers, has exposed a new level of crisis in air travel.

A few days ago, Warren Buffett, the most successful investor in history, said he would retire as C.E.O. of Berkshire Hathaway, the conglomerate that he built into a trillion-dollar colossus.

When Taffy Brodesser-Akner became a writer, Mr. Lindenblatt, the father of one of her oldest friends, began asking to tell his story of survival during the Holocaust in one of the magazines or newspapers she wrote for. He took pride in telling his story, in making sure he fulfilled what he felt was the obligation of all Holocaust survivors, which was to remind the world what had happened to the Jews. His daughter Ilana knew it was a long shot but felt obligated to pass on the request — it was her father, after all. Taffy declined because after a life hearing about the Holocaust, she said, she was “all Holocausted out.” But, years later, when she learned of Mr. Lindenblatt’s imminent passing, Taffy asked herself what would become of stories like his if the generation of hers that was supposed to inherit them had taken the privilege that came with another generation’s survival and decided not to listen? So here it is, an old Jewish story about the Holocaust and a man who somehow survived the pernicious, organized and intentional genocide of the Jews. But right behind it, just two generations later, is another story, one about the children and grandchildren who have been so malformed by the stories that are their lineage that some of them made just as eager work of running from it, only to find themselves, same as anything you run from, having to deal with it anyway.

Jeanna Smialek, who covers the U.S. economy for The Times, will be 33 in a few weeks; she is part of a cohort born in 1990 and 1991 that makes up the peak of America’s population. At every life stage, that microgeneration has stretched a system that was often too small to accommodate it, leaving its members — so-called peak millennials — with outsize economic power but also a fight to get ahead. Guest: Jeanna Smialek, a U.S. economy correspondent for The New York Times.
