Older Americans Are Quitting the Workforce, and AI Is Filling the Gap

The U.S. labor force participation rate for civilians aged 55 and older dropped to 36.9% last month from 38.1% a year earlier, a contraction that RSM US Chief Economist Joe Brusuelas called "a historic exit from the American labor market" in a Monday note.

That exit coincides with record corporate AI investment. Gartner forecasts global AI spending will jump 47% this year to $2.6 trillion, up from $1.76 trillion in 2025. By 2030, the research firm expects outlays to reach $5.62 trillion.

What is driving the participation decline?

Brusuelas attributes the drop to Baby Boomer retirements and tightened immigration under President Donald Trump. The share of Americans 65 and older has climbed to 18% from 12% in 2005, reshaping the working-age pool.

The White House said the U.S. recorded negative net migration in 2025 for the first time in at least 50 years. The Trump administration has deported more than 605,000 people, with 1.9 million having left voluntarily.

"A quarter of a century ago, when it became clear that the American economy would age as the boomers left the labor force, economists assured themselves that Washington would turn to immigration," Brusuelas said. "That turned out not to be the case."

What does this mean for individual workers?

The combined effect is a 0.77% year-over-year contraction in labor supply, Brusuelas said. That shift explains why the economy now needs only about 35,000 net new jobs per month to stay stable, a fraction of historical hiring requirements.

For mid-career professionals, the math lowers the bar for job-search leverage while raising the cost of specialized skills that employers cannot automate easily.

What does the latest jobs report show?

The Labor Department reported Friday that the U.S. shed 23,000 jobs last month. Revisions cut 103,000 positions from May and June combined. The unemployment rate still dipped to 4.1% in July from 4.2% in June, per the Bureau of Labor Statistics.

Why is AI demand looking more durable?

A shrinking workforce offers a counterargument to investors worried that AI spending will outrun buyer demand. Brusuelas frames retiring boomers and tighter borders as a structural shortage that businesses must solve with software.

"American businesses will need to turn to technology as a substitute for labor," he wrote. "That means more artificial intelligence, not less."

Workers in roles exposed to automation should expect headcount and productivity to keep decoupling, with premiums for talent that deploys AI rather than competes with it. If participation continues sliding toward the demographic shift demographers have forecast, the substitution story becomes a multi-year capex thesis for AI vendors.
