Donald Trump rode a wave of white male support to the White House—and his photo ops show he’s still largely surrounded by it while in office. The gender pay gap and the assault on reproductive rights continues, as one popular sign at the Women’s March on Washington said, “I can’t believe I still have to protest this fucking shit.” Now, a bit more troubling news for feminists: New research finds that millennial men are more supportive of old-school marriages and stay-at-home wives than the young men of 20 years ago.

While the much-used (abused?) term millennial technically applies to people born between 1982 and 2000, younger millennials (ages 18 to 25) have more retrograde views on marriage and family, according to a new report from the Council on Contemporary Families. It found that 58 percent of high school seniors in 2014 agreed that the best family was one where the man was the main income earner and the woman took care of the home; in 1994, only 42 percent felt the same. Similarly, almost 40 percent of 2014’s high school seniors said “the husband should make all the important decisions in the family,” while fewer than 30 percent in 1994 held that belief.

Another paper by the Council found that young men’s worldviews have become more conservative over time on a few issues than young women’s: In 1994, 83 percent of young men were against Father Knows Best–style families, in which dads work and moms stay home; in 2014, that number fell sharply to 55 percent. And while women’s support of old-school marriage also rose over the last 20 years, the shift in opinion was less drastic: In 1994, 85 percent of young women rejected the idea that traditional marriage-work arrangements was best, compared to 72 percent in 2014.

One can’t call it the Trump Effect, but this rise of the traditional macho man may be part of the cause of the president’s win, as millennial men also proved themselves less likely to support a woman as commander in chief: Exit polls have found that 63 percent of young women voted for Hillary Clinton, compared to 47 percent of millennial men.

Why, in some cases, are millennial dude-bros even more traditional than their dads? One political scientist told The New York Times that it’s about compensating “for men’s loss of dominance in the work world.” Try not to roll your eyes, everyone else, but these men came of age right after the financial crisis and may have seen their fathers losing their jobs and struggling financially, as women began to outpace men in college enrollment and make up about half of the workforce.

But millennial men’s support of traditional families may not be maliciously antifeminist, but, perhaps, a statement on the U.S.’s glaring lack of policies to benefit working families. Yes, the U.S., proverbial leader of the free world, ranks among the worst in granting family leave to its mighty workforce, and in the absence of those policies, still more data that has found that American parents are unhappier than those around the world.

It’s no wonder, then, that “some young people think that more traditional family arrangements might make life less stressful,” noted Stephanie Coontz, director of research and public education for the Council, in an article written for the Times.

All this said, it seems Ivanka Trump, self-appointed White House chief of advancing working women, has her work cut out for her.
