The authors explain that when inequality hit a low in the 1970s, there wasn’t that much of a gap between what someone earned with or without a college degree. Strict parenting gave way to an era of “permissive parenting” — giving children lots of freedom with little oversight. Why spend 18 years nagging kids to succeed if the rewards weren’t worth it?
In the 1980s, however, inequality increased sharply in Western countries, especially the United States, and the gap between white- and blue-collar pay widened. Permissive parenting was replaced by helicopter parenting. Middle- and upper-class parents who’d gone to public schools and spent evenings playing kickball in the neighborhood began elbowing their toddlers into fast-track preschools and spending evenings monitoring their homework and chauffeuring them to activities.
American parents eventually increased their hands-on caregiving by about 12 hours a week, compared with the 1970s. Dutch, Spanish, Italian, Canadian and British parents ramped up their child care, too. (In Japan, hyper-involved mothers are known as “monster parents.”)
