In the early 1980s, the majority of private-sector workers with a retirement plan had a guaranteed pension, a check for life, funded by the employer, insulated from market swings. Then corporations discovered a provision buried in the Revenue Act of 1978 called the 401(k), and spent the next 40 years replacing guaranteed pensions with individual investment accounts. By 2024, only 15% of private-industry workers have access to a defined benefit pension plan, according to the Bureau of Labor Statistics. One in three American adults has no assets specifically designated for retirement, the Federal Reserve found in 2024. And just 35% of non-retirees believe their retirement savings are on track.
How the Pension Disappeared
A defined benefit pension is exactly what the name says: the employer promises a specific monthly payment for the rest of your life. The investment risk belongs to the company. You work for 30 years; you know what you will receive. That model covered most of the private workforce through the 1970s. Then came the 401(k).
Congress inserted the 401(k) provision in 1978 as a niche tax shelter. Benefits consultants and HR departments quickly recognized it as an exit ramp from pension obligations. Defined benefit plans are expensive: the employer funds them, invests the assets, and absorbs the loss when markets drop. A 401(k) shifts the contribution burden, the investment decisions, and the market risk entirely onto the worker. When the stock market fell 34% in 2020 and 19% in 2022, workers approaching retirement absorbed those losses themselves. When corporations post record profits, the pension obligation is already off the balance sheet.
The Economic Policy Institute, which has tracked this transformation for decades, concluded: "The shift from pensions to account-type savings plans has been a disaster for lower-income, Black, Hispanic, non-college-educated, and single workers, who together add up to a majority of the American population."
"At a time when more than half of older Americans have no retirement savings and more than 50 percent of our nation's seniors are trying to survive on an income of less than $30,000 a year, we must address the retirement crisis facing working class Americans."

Who the 401(k) Leaves Behind
The average 401(k) balance in 2025 was roughly $148,000, a figure that appears regularly as evidence the system is working. The median balance was less than the price of a new car. The average is skewed by the top quarter of earners with large balances; the typical worker holds far less. Vanguard, which administers millions of 401(k) accounts, noted that the average balance reflects savers at roughly the 75th percentile, meaning three in four workers hold less than the number making headlines.
The retirement access gap runs sharply along racial lines. The Federal Reserve's 2024 survey found that 68% of white adults have a tax-preferred retirement account, compared with 52% of Black adults and 46% of Hispanic adults. Black and Hispanic adults were also significantly less likely to believe their retirement savings were on track. These gaps widened after 401(k)s replaced pensions. Defined benefit pensions did not require workers to opt in, contribute from take-home pay, or navigate investment menus. Workers were enrolled automatically. The 401(k) model requires all three steps, and it rewards workers who start young, earn steadily, and never need to stop contributing.
Workers without access to an employer plan at all, common in service, gig, and agricultural jobs, have no path into the 401(k) system even if they can afford to contribute. The Federal Reserve found that 29% of adults have a defined benefit pension of any kind; among adults aged 25 to 54, that share drops to 20%.
The Balanced Alternative
The defined benefit model has not disappeared. Federal employees still receive it. Military personnel receive it. Teachers in most states receive it. The workers who kept their pensions are, broadly, the workers with unions or civil-service protections that prevented employers from making the unilateral switch. Private-sector workers without those protections got the 401(k) instead.
Countries including the Netherlands, Denmark, and Australia require employers to fund retirement at guaranteed minimum contribution rates, with mandatory enrollment and benefits that deliver income for life. Their old-age poverty rates are a fraction of the U.S. rate. None of these countries eliminated private investment or abolished market mechanisms. They regulated the floor of the employment contract to require retirement contributions the way the U.S. requires workers' compensation insurance, as a cost of hiring, not a discretionary benefit.
The 40-year 401(k) experiment produced record balances for the top quarter of the workforce and an accelerating retirement crisis for everyone below them. Expanding mandatory employer contributions, restoring defined benefit access to private-sector workers through tax incentives and labor standards, and strengthening Social Security are the policy tools available. Every other wealthy country built a retirement floor. The U.S. has the blueprint. It needs the political will to use it.
