Social Security Didn’t Suddenly Break. Congress Stopped Fixing It
Congress repaired Social Security in 1983. Then inequality weakened the repair, and mass deportation began draining the system.
Every few months another headline warns that Social Security is running out of money, like it caught everyone by surprise.
It didn’t.
The people who designed Social Security in 1935 knew millions of Americans were already living well beyond age 65. They studied the country’s changing age distribution and built those projections into the program.
When Social Security approached a genuine financing crisis in 1983, Congress acted again. Lawmakers adopted a bipartisan package intended to restore solvency over the program’s 75-year forecasting period.
What’s happening to Social Security right now isn’t a mystery that snuck up on Washington. The 1983 repair wasn’t undone by a demographic miss. It was undone by the same force behind today’s headlines about income inequality, and it’s now being compounded by new policy choices draining revenue from the system even faster.
What They Knew From Day One
The myth goes that Social Security was designed for people who would die before collecting it, because life expectancy at birth in 1935 was around 61.
That number is real but misleading. It was pulled down by infant and childhood mortality in that era. The actuaries designing Social Security understood that life expectancy at birth was not the relevant measure. What mattered was how long adults were likely to live, and how many Americans were already reaching retirement age.
There were approximately 7.8 million Americans age 65 or older when the Social Security Act passed in 1935. The government’s own actuarial estimates projected that the number would reach 8.3 million by 1940, when monthly benefits began.1
An aging America wasn’t a blind spot. It was built into the calculations from the start.
What changed dramatically was the ratio of workers paying into Social Security to beneficiaries receiving payments.
In 1950, there were approximately 16.5 covered workers for every beneficiary. By 1960, the ratio had fallen to 5.1 to 1.2 Today, it is about 2.7 to 1. 3
That is the number that places pressure on a largely pay-as-you-go system. And it did not fall overnight. It declined over decades as the enormous baby-boom generation aged out of the workforce and was followed by generations with lower birth rates.
The Fix That Was Supposed to Last
By the early 1980s, that math had caught up with the trust fund, and Congress knew it. The Old-Age and Survivors Insurance Trust Fund was nearing depletion and had to borrow temporarily from the disability and Medicare trust funds to continue making payments. 4
In 1981, lawmakers created the National Commission on Social Security Reform, chaired by Alan Greenspan, to solve a financing crisis everyone could see coming.5 The commission’s recommendations helped form the Social Security Amendments of 1983, which Congress passed by overwhelming bipartisan margins. 6
The law gradually raised the full retirement age from 65 to 67. It subjected a portion of benefits received by higher-income retirees to federal income taxation and directed that revenue back into the trust funds. It also expanded Social Security coverage to additional groups of workers. 7
The 1983 Trustees Report projected that the combined trust funds would remain solvent throughout the following 75 years, until roughly the early 2060s. 8
But one critical part of that projection did not hold.
The Cap That Quietly Stopped Working
In 1983, approximately 90 percent of all earnings covered by Social Security fell below the taxable maximum and were therefore subject to Social Security payroll taxes.
The taxable maximum was indexed to average wage growth, with the expectation that this would keep roughly 90 percent of covered earnings inside the system’s tax base.
That expectation failed because wages did not grow evenly. Income at the top rose much faster than average wages. Because the taxable maximum follows average wage growth rather than the much faster growth of earnings at the top, an increasing share of the nation’s wages escaped Social Security taxation. 9
By 2000, the taxable share had fallen to about 82.5 percent, and it has stayed close to that level since, sitting at roughly 83 percent in the most recent published data10
The cap itself still rises every year. In 2026, Social Security taxes apply to the first $184,500 of a worker’s earnings, up from $176,100 in 2025. Only about 6 percent of covered workers earn enough in a given year to reach that cap. 11
But that small group receives a disproportionately large share of the nation’s wage income.
Below the cap, every dollar of wages is taxed for Social Security. Above it, no additional Social Security payroll tax is collected.
Nobody held a vote to abandon the 90 percent target. The erosion happened quietly, year after year, as income became more concentrated at the top and Congress left the 1983 formula untouched.
The New Accelerant
That’s the slow leak. Here’s the fast one.
The 2026 Social Security Trustees Report projects that the combined retirement and disability trust-fund reserves will be depleted in 2034. At that point, continuing payroll-tax income would still cover approximately 83 percent of scheduled benefits, but without congressional action, benefits could no longer be paid in full. 12
That’s before fully accounting for the scale of the current deportation campaign. A Penn Wharton Budget Model analysis examined what large-scale deportation would do to Social Security’s finances. Under its most extensive scenario, ten years of deportations followed by the permanent elimination of unauthorized immigration, Social Security’s shortfall would grow by approximately $133 billion over ten years and $884 billion over thirty years, moving trust-fund depletion forward by roughly six months.
Here’s the part that should stop us. Undocumented immigrants contribute billions of dollars each year to a system from which most will never receive benefits. Penn Wharton estimates that unauthorized workers paid approximately $24 billion in Social Security taxes in 2024, despite generally being ineligible to collect benefits unless they later obtain qualifying legal status. 13 That’s money in, with almost nothing scheduled to come back out.
Removing those workers does not repair Social Security’s finances. It reduces the number of people paying into the system, shrinks payroll-tax revenue, and accelerates the shortfall. That is not an accidental consequence of an unforeseeable demographic shift. It is the predictable result of a policy choice being made in full view of the numbers.
Nobody Gets to Say They Didn’t Know
Here’s what makes this different from 1935, or even 1983.
Nobody today can claim the numbers were hidden.
The Social Security trustees publish a report every single year. The actuarial tables are online. The decline in the share of wages subject to payroll taxes has been documented for decades. The positive contribution of immigration to Social Security’s finances is well established.
The 1983 repair did not fail because its authors forgot that Americans would grow older. According to Social Security’s own chief actuary, the nation’s age distribution generally developed close to what the reformers expected. 14
The projection deteriorated in large part because earnings became far more concentrated at the top than anticipated, leaving a growing share of wages outside the payroll-tax system. Economic growth and labor productivity also performed worse than expected.
And now, on top of that, the workers helping prop up what’s left of the tax base are being deported instead of thanked for keeping the math working as long as it has.
Social Security was not blindsided by a future nobody imagined.
Its designers saw aging coming. Congress repaired the system when a crisis arrived. That repair later weakened in ways that have been documented, measured and publicly reported for decades.
The system can still be repaired again. But every year Congress delays makes the eventual choices harder, the solutions more expensive and the risk to beneficiaries more immediate. If lawmakers continue to do nothing, the warning will become a deadline, and millions of Americans will pay the price for a crisis their government saw coming.
They knew.
They fixed it once.
Then they stopped maintaining it and chose policies that made the damage worse.
