Low US Fertility, Aging and AI Threaten Long-Term Fiscal Stability

The latest federal data paints a sobering picture of America's demographic future. Last week the government reported that the US fertility rate fell to a record low of 1.57 children per woman in 2025, slipping below even the pessimistic projections issued by the Congressional Budget Office just months earlier. The number sits well under the 2.1 births per woman required to keep the population stable without immigration, a threshold the United States has not reached since the depths of the Great Recession.

This is not the overpopulation nightmare warned about by Paul Ehrlich in the 1960s. Instead the country faces the opposite problem: too few young people entering the workforce to support a rapidly swelling cohort of retirees. In 2000 there were roughly 24 Americans aged 65 and older for every 100 working-age adults. By mid-century that ratio will climb to 43, according to CBO forecasts. The fiscal consequences are already baked into federal projections. Spending on Medicare and Social Security, which stood at 6 percent of GDP at the turn of the century, is expected to reach 12.7 percent by 2055, driven largely by demographic aging rather than expanded benefits. The resulting pressure on deficits and debt threatens to crowd out investment in everything from infrastructure to education at precisely the moment when global competition is intensifying.

The fertility collapse is not occurring in a vacuum. Decades of rising child-rearing costs, stagnant wages for large segments of the population, crushing student debt, and the absence of robust paid family leave have all contributed to young Americans delaying or forgoing parenthood. Artificial intelligence, meanwhile, is already reshaping labor markets in ways that could either mitigate or exacerbate the crunch. While optimists argue AI-driven productivity gains could help a smaller workforce sustain economic growth, skeptics warn that concentrated gains in a few tech sectors will do little to ease the care burdens facing an older society or address the economic insecurity that keeps birth rates depressed.

Into this breach have stepped conservative policy shops with prescriptions that lean heavily on government intervention to engineer traditional family structures. A January report from the Heritage Foundation titled “Saving America by Saving the Family” calls for an array of federal programs to reverse declining marriage and birth rates. Among the proposals is a government-backed “marriage bootcamp” run by the Department of Health and Human Services in partnership with churches and private donors. Unmarried couples with children would be recruited through taxpayer-funded advertising campaigns, attend the program, and emerge with a communal wedding ceremony, a mentor couple, and a $5,000 cash payment to “encourage family formation.”

The report also advocates expanding so-called Trump Accounts that seed every newborn with $1,000, and creating new “New Early Starter Trust” accounts seeded with at least $2,500 at birth. These funds would be accessible, with tax advantages, upon marriage or turning 30, explicitly designed to incentivize earlier unions. Heritage further recommends a federal propaganda effort promoting messages such as “Give her a ring before she gives you a baby,” along with new HHS initiatives in relationship education, parenting skills, and father involvement.

The authors concede that previous government-backed marriage promotion programs produced only “modest” results, yet they insist larger, better-funded versions are essential to restoring the family as the “center of American life.” The ideological thrust is unmistakable: conservatives who spent years railing against government overreach in the economy now appear comfortable with Washington playing matchmaker, banker, and propagandist when it comes to reproductive choices.

Critics argue these schemes misdiagnose the problem. Fertility decline is a feature of virtually every advanced economy, driven by women’s increased educational and career opportunities, the high cost of housing and childcare, and genuine uncertainty about the future in an era of climate disruption and technological upheaval. Offering $5,000 wedding bonuses or marriage bootcamps does nothing to address the $20,000 annual cost of childcare in many cities, the mountain of student loans burdening millennials and Gen Z, or the lack of paid parental leave that forces impossible trade-offs between work and family.

Nor do the proposals grapple with the reality that many Americans are not avoiding children out of moral failing but because they are making rational calculations in an economy that treats working families as an afterthought. The same conservative policymakers who champion these natalist schemes have consistently opposed universal pre-K, paid family leave, and affordable housing measures that could make parenthood more viable for working- and middle-class Americans. Instead they offer conditional cash tied to traditional marriage, a vision that feels less like pro-family policy than an attempt to resurrect a particular cultural model through federal engineering.

The United States has long relied on immigration to offset low native birth rates and sustain its dynamic labor force. Yet that avenue faces fierce political headwinds from the same quarters now decrying population decline. The result is a policy incoherence: alarm over demographic collapse on one hand, resistance to the most proven remedy on the other.

Whether conservative family engineering experiments will move the fertility needle remains doubtful. History suggests that financial incentives and moral exhortations produce only marginal effects when stacked against deeper economic and social forces. What is clear is that the aging of America is no longer a distant projection. It is here, measurable in last week’s fertility statistics and in the CBO’s sobering long-term budget forecasts. How the country chooses to respond, whether through genuine support for families or through ideological experiments in social engineering, will help determine whether the next quarter-century brings managed adaptation or mounting fiscal and social strain.
