American manhood used to follow a script: leave home, get a job, build a life. Fortune reports that for a growing share of men without college degrees, the script is being rewritten by something less glamorous than culture wars: rents.

Start with the numbers. One in six noncollege-educated men (16%) now live with their parents, compared with 8% of college-educated men. And what matters even more is what happens after they move in: men living with their parents are 20 percentage points less likely to be in the labor force than those living independently. In the same research, a 10% increase in local rents raises the likelihood a non-college-educated man moves in with his parents by 1.1 percentage points, and is associated with a 0.5 percentage point decline in labor force participation.

This is not just a “some people are struggling” story. It is a labor market story with a housing pipeline problem built in. Penrose, a graduate student fellow at the American Institute for Boys and Men, followed six decades of U.S. Census data and drew a direct line between higher housing costs and the decline of male labor force participation. Her headline framing is blunt: “There are very real economic forces that are limiting the options for noncollege-educated men in the United States,” Penrose told Fortune, adding that “Some of what we're seeing is simply rational responses to a system that's pricing them out.”

Why housing? Because in practice, rent is not just a bill. It is the price of independence. Penrose’s paper suggests the rent shock hits hardest where supply is constrained. She used geographic constraints like mountains, coastlines, and lakes as a research instrument, basically treating nature like a “control variable.” The result: in areas where terrain limits construction and squeezes housing supply, costs are higher for reasons unrelated to local wages or job prospects. In other words, higher rents can be structural and unavoidable, not a sign that local workers are booming.

Zoom out to the long arc. Since 1960, real rents in the United States have risen 150%. Over that same period, wages for men without college degrees have barely moved, with Penrose’s paper pointing to automation, globalization, and the collapse of manufacturing. Put those trends together and you get a brutal incentive mismatch: the price of starting adulthood keeps climbing while earning power for noncollege men is not keeping up. Then, if parents have the housing wealth to absorb the gap, the family does the buffering.

That “buffer” part is the other crucial mechanism. Penrose argues that baby boomer parents, sitting on significant housing wealth, are better positioned than ever to absorb adult children. Economists call this kind of behavior a “normal good,” meaning spending increases as income rises. Penrose told Fortune: “Providing for your adult children when they're priced out of the housing market is kind of a ‘normal good,' as economists call it, something people spend more on as they get richer.” She ties it to the inequality between generations: “Parents are earning more, and their sons are earning less.”

The National Association of Realtors adds a real-world datapoint to the same theme. Brandi Snowden, the organization’s director of member and consumer survey research, told Fortune that baby boomers continued to make up the largest share of recent homebuyers, and NAR’s 2026 Generation Trends report showed one-quarter of baby boomers purchased a multigenerational home recently. Snowden said the motivation includes caring for aging parents or relatives and accommodating adult children moving back in or never leaving.

Now connect this to labor force behavior. Penrose isolates the post-move outcome: men living with parents are 20 percentage points less likely to be in the labor force than those living independently. For the labor market impact, Penrose’s estimates suggest housing costs could explain roughly a third of the total employment decline among noncollege men. Winship, a senior fellow and director of the Center on Opportunity and Social Mobility at the American Enterprise Institute, points out why today’s disadvantage may be harsher than in the 1960s: fewer noncollege men exist now, but the education gap is bigger, with the share of young adults with a bachelor’s degree “up to 40% or so now,” versus much lower levels in the past. “They are a more disadvantaged group than they were in previous generations,” Winship told Fortune.

So what do these men do once they move home? The data cuts against a comforting storyline. Penrose said pushback sometimes argues men use living at home as a “launchpad.” “That doesn't seem to be the case,” Penrose told Fortune. “These men who are living with their parents are completely detached from the labor market.” Among nonworking men at home, a quarter have never held a job at all, up from one in five in 1980. Penrose also notes one in five noncollege men in their early thirties live with their parents, and the rate stays elevated into their forties, with roughly 14% at age 40.

There is policy electricity under all this. Penrose writes that zoning restrictions and limits on construction can suppress workforce participation among those least equipped to absorb higher housing costs. In her report, she argues: “Policies that restrict housing construction inadvertently weaken labor force participation by raising the price of independence.” She adds a broader framing for policymakers: housing policy is not only affordability, it is access to the labor market. Winship agrees, pointing to high-cost, job-rich metros as the paradox zone. “High cost of living cities like New York and San Francisco are often where people can find more job opportunities,” Winship told Fortune, “but it comes with the double-edged sword of higher rents.” He calls the villain “land use regulations and zoning that constrain how much housing can be built,” and notes that the cities with more amenities and economic dynamism can have the worst zoning constraints.

And then comes the second-order question leaders should care about: what happens when work disconnects from independence? Fortune frames this as the broader outcome, including marriage rates. The setup in the reporting is clear: women have outnumbered men in the workforce for the third time in history, and that shift is intersecting with the labor market pullback among noncollege men. Even before you get to the marriage details, the chain is already laid: higher rents push more men home; living at home correlates with falling out of the labor force; and a labor disconnect at the ages when many form long-term partnerships changes the odds. If you are advising, investing, or operating in the economy, this is the kind of structural drag that does not announce itself with headlines until it has already made the workforce smaller and more disconnected.
