That is the best clickbait the headline writer found to describe Stephanie Coontz' opinion piece in the New York Times.
Coontz writes about the findings of opinion surveys which suggest that the age group between 18 and 25 in the US might hold more patriarchal views about the family than older age group:
Using a survey that has monitored the attitudes of high school seniors for nearly 40 years, the sociologists Joanna Pepin and David Cotter find that the proportion of young people holding egalitarian views about gender relationships rose steadily from 1977 to the mid-1990s but has fallen since. In 1994, only 42 percent of high school seniors agreed that the best family was one where the man was the main income earner and the woman took care of the home. But in 2014, 58 percent of seniors said they preferred that arrangement. In 1994, fewer than 30 percent of high school seniors thought “the husband should make all the important decisions in the family.” By 2014, nearly 40 percent subscribed to that premise.
A different survey found a similar trend, in this case concentrated mainly among men. In 1994, 83 percent of young men rejected the superiority of the male-breadwinner family. By 2014 that had fallen to 55 percent. Women’s disagreement fell far less, from 85 percent in 1994 to 72 percent in 2014. Since 1994, young women’s confidence that employed women are just as good mothers as stay-at-home moms has continued to inch up, but young men’s has fallen. In fact, by 2014, men aged 18 to 25 were more traditional than their elders.
Weird stuff. I read both the linked study summaries and noticed that the second one used a very small sample for the age group 18-25 (n=200) (1) so I'm not going to consider its findings any further, but instead concentrate on the Pepin-Cotter findings.
So what are those findings about high school seniors in general?
