The Trump administration marries insane ideas to gross, bullying tactics. But even when this administration stumbles upon an idea that is not deranged, illegal or immoral, it has the capacity to do great harm. I’m thinking of the reported plans to encourage marriage and motherhood. The administration is considering proposals to award mothers $5,000 “baby bonuses,” to reserve 30% of Fulbright scholarships to parents, to reduce the costs of IVF (not clear how) and to fund programs to educate women about ovulation cycles (I kid you not).

I’ve been promoting marriage for decades, not as part of a religious agenda but as the result of studying the social science literature demonstrating that marriage makes adults happier than non-marriage and that stable, two-parent homes are the very best environment for raising children, building thriving neighborhoods and reducing crime, homelessness and substance abuse.

The Trump administration cannot adopt this message without turning it rancid. If you hope to persuade people, you must start by showing good faith — that your intentions for them are good. This crowd has displayed open contempt for women — at least those women who vote for the other party or otherwise assert their individuality. In light of the president’s apparent requirement that any nominee for a major cabinet role have at least one serious accusation of sexual misconduct, the vice president’s sneers about “childless cat ladies” seem mild. Matt Gaetz, Robert F. Kennedy Jr., Pete Hegseth and Linda McMahon all trailed accusations that would have been disqualifying in any other administration. Only Gaetz was undone.

But then, the thrice-married, adulterous president himself has been found legally liable for sexual assault in the E. Jean Carroll case and has been accused of similar behavior half a dozen or so times by other women.

The Trump crowd’s approach to fertility is not the joy of parenthood or the warmth of close families. It’s more like the “great replacement” theory made flesh. As Elon Musk admits, he wants a “legion” of offspring “before the apocalypse” and is creating a harem to achieve it. He has been married but is also father to at least 14 children by four different women and willing to outsource his semen upon request.

You don’t convince women in a free country to have more babies for the sake of the fatherland. If you want to encourage family formation and increase the birth rate, you can’t treat women as breeder mares. It helps to model good behavior. That includes being good husbands who don’t cheat on their wives, good fathers who actually live with their kids, and good parents who don’t commit or condone adultery.

Baby bonuses have been tried in other countries with poor results. Hungary, Singapore, South Korea and Russia have all adopted policies to support families that are far more generous than what the Trump administration is considering, but the results have been disappointing.

There are many things governments can do to ease the burden on parents — tax credits, parental leave and banning smartphones in schools, among other ideas — but policymakers should keep their expectations in check about the effect these initiatives will have on fertility. If they just make family life easier and better, that’s a good start. But frankly, we’d all be better off if the Trump people stay far away from family policy, lest they besmirch it.
