It almost seems as if we’re trying to raise a nation of “adultescents.” Illustration by Christoph Abbrederis

In 2004, Carolina Izquierdo, an anthropologist at the University of California, Los Angeles, spent several months with the Matsigenka, a tribe of about twelve thousand people who live in the Peruvian Amazon. The Matsigenka hunt for monkeys and parrots, grow yucca and bananas, and build houses that they roof with the leaves of a particular kind of palm tree, known as a kapashi. At one point, Izquierdo decided to accompany a local family on a leaf-gathering expedition down the Urubamba River.

A member of another family, Yanira, asked if she could come along. Izquierdo and the others spent five days on the river. Although Yanira had no clear role in the group, she quickly found ways to make herself useful. Twice a day, she swept the sand off the sleeping mats, and she helped stack the kapashi leaves for transport back to the village. In the evening, she fished for crustaceans, which she cleaned, boiled, and served to the others. Calm and self-possessed, Yanira “asked for nothing,” Izquierdo later recalled. The girl’s behavior made a strong impression on the anthropologist because at the time of the trip Yanira was just six years old.

While Izquierdo was doing field work among the Matsigenka, she was also involved in an anthropological study closer to home. A colleague of hers, Elinor Ochs, had recruited thirty-two middle-class families for a study of life in twenty-first-century Los Angeles. Ochs had arranged to have the families filmed as they ate, fought, made up, and did the dishes.

Izquierdo and Ochs shared an interest in many ethnographic issues, including child rearing. How did parents in different cultures train young people to assume adult responsibilities? In the case of the Angelenos, they mostly didn’t. In the L.A. families observed, no child routinely performed household chores without being instructed to. Often, the kids had to be begged to attempt the simplest tasks; often, they still refused. In one fairly typical encounter, a father asked his eight-year-old son five times to please go take a bath or a shower. After the fifth plea went unheeded, the father picked the boy up and carried him into the bathroom. A few minutes later, the kid, still unwashed, wandered into another room to play a video game.

In another representative encounter, an eight-year-old girl sat down at the dining table. Finding that no silverware had been laid out for her, she demanded, “How am I supposed to eat?” Although the girl clearly knew where the silverware was kept, her father got up to get it for her.

In a third episode captured on tape, a boy named Ben was supposed to leave the house with his parents. But he couldn’t get his feet into his sneakers, because the laces were tied. He handed one of the shoes to his father: “Untie it!” His father suggested that he ask nicely.

“Can you untie it?” Ben replied. After more back-and-forth, his father untied Ben’s sneakers. Ben put them on, then asked his father to retie them. “You tie your shoes and let’s go,’’ his father finally exploded. Ben was unfazed. “I’m just asking,’’ he said.

A few years ago, Izquierdo and Ochs wrote an article for Ethos, the journal of the Society of Psychological Anthropology, in which they described Yanira’s conduct during the trip down the river and Ben’s exchange with his dad. “Juxtaposition of these developmental stories begs for an account of responsibility in childhood,” they wrote. Why do Matsigenka children “help their families at home more than L.A. children?” And “Why do L.A. adult family members help their children at home more than do Matsigenka?” Though not phrased in exactly such terms, questions like these are being asked—silently, imploringly, despairingly—every single day by parents from Anchorage to Miami. Why, why, why?

With the exception of the imperial offspring of the Ming dynasty and the dauphins of pre-Revolutionary France, contemporary American kids may represent the most indulged young people in the history of the world. It’s not just that they’ve been given unprecedented amounts of stuff—clothes, toys, cameras, skis, computers, televisions, cell phones, PlayStations, iPods. (The market for Burberry Baby and other forms of kiddie “couture” has reportedly been growing by ten per cent a year.) They’ve also been granted unprecedented authority. “Parents want their kids’ approval, a reversal of the past ideal of children striving for their parents’ approval,” Jean Twenge and W. Keith Campbell, both professors of psychology, have written. In many middle-class families, children have one, two, sometimes three adults at their beck and call. This is a social experiment on a grand scale, and a growing number of adults fear that it isn’t working out so well: according to one poll, commissioned by Time and CNN, two-thirds of American parents think that their children are spoiled.

The notion that we may be raising a generation of kids who can’t, or at least won’t, tie their own shoes has given rise to a new genre of parenting books. Their titles tend to be either dolorous (“The Price of Privilege”) or downright hostile (“The Narcissism Epidemic,” “Mean Moms Rule,” “A Nation of Wimps”). The books are less how-to guides than how-not-to’s: how not to give in to your toddler, how not to intervene whenever your teen-ager looks bored, how not to spend two hundred thousand dollars on tuition only to find your twenty-something graduate back at home, drinking all your beer.

Not long ago, Sally Koslow, a former editor-in-chief of McCall’s, discovered herself in this last situation. After four years in college and two on the West Coast, her son Jed moved back to Manhattan and settled into his old room in the family’s apartment, together with thirty-four boxes of vinyl LPs. Unemployed, Jed liked to stay out late, sleep until noon, and wander around in his boxers. Koslow set out to try to understand why he and so many of his peers seemed stuck in what she regarded as permanent “adultescence.” She concluded that one of the reasons is the lousy economy. Another is parents like her.

“Our offspring have simply leveraged our braggadocio, good intentions, and overinvestment,” Koslow writes in her new book, “Slouching Toward Adulthood: Observations from the Not-So-Empty Nest” (Viking). They inhabit “a broad savannah of entitlement that we’ve watered, landscaped, and hired gardeners to maintain.” She recommends letting the grasslands revert to forest: “The best way for a lot of us to show our love would be to learn to un-mother and un-father.” One practical tip that she offers is to do nothing when your adult child finally decides to move out. In the process of schlepping Jed’s stuff to an apartment in Carroll Gardens, Koslow’s husband tore a tendon and ended up in emergency surgery.

Madeline Levine, a psychologist who lives outside San Francisco, specializes in treating young adults. In “Teach Your Children Well: Parenting for Authentic Success” (HarperCollins), she argues that we do too much for our kids because we overestimate our influence. “Never before have parents been so (mistakenly) convinced that their every move has a ripple effect into their child’s future success,” she writes. Paradoxically, Levine maintains, by working so hard to help our kids we end up holding them back.
