Social Security turns 90, but faces an uncertain future

Ninety years ago this week, President Franklin D. Roosevelt signed the Social Security Act into law, establishing a major commitment: after a lifetime of work, Americans could count on a baseline of financial protection in old age.

Originally designed as a retirement safety net for seniors, Social Security has evolved into a multifaceted program that also supports disabled Americans, survivors of deceased workers, and dependent family members. Today, it pays benefits to more than 67 million people, serving as the single largest source of retirement income for U.S. seniors — and, for many, the only guaranteed one.

Yet this milestone comes with a looming warning: without changes, Social Security’s trust funds are projected to be depleted by 2034, according to the latest Social Security Trustees Report. If Congress does not act, the program would still pay benefits, but only about 80% of what is promised.

Uncertain future

“As we mark the 90th anniversary of Social Security, we celebrate one of the most successful and enduring programs in American history,” said Dan Doonan, executive director of the National Institute on Retirement Security (NIRS). “For nine decades, Social Security has provided a critical foundation of financial security for millions of Americans. Today, it’s a promise worth keeping.”

Doonan and other retirement policy experts emphasize that Social Security is not a luxury — it is essential for millions. According to NIRS research, roughly one in four seniors relies on it for nearly all of their income, and about half depend on it for at least 50%.

But keeping the system healthy will require political compromise and economic foresight. “We must not take this program for granted,” Doonan warned. “Now is the time for Congress to come together and develop a bipartisan solution that protects current retirees and future generations.”

The funding challenge

Social Security is funded mainly through payroll taxes under the Federal Insurance Contributions Act (FICA). But demographic shifts — longer lifespans, lower birth rates, and the retirement of the massive baby boomer generation — mean fewer workers are paying into the system for each retiree drawing benefits.

In 1960, there were more than five workers per beneficiary; today, there are around 2.7, and that ratio is expected to shrink further. Combined with slower wage growth and widening income inequality, the payroll tax base is under stress.

Policy analysts have laid out potential fixes, including:

  • Raising or eliminating the cap on taxable income (in 2025, earnings above $168,600 are exempt from Social Security tax).
  • Gradually increasing the payroll tax rate shared by employers and employees.
  • Adjusting the full retirement age or benefit formulas for higher earners.
  • Diversifying trust fund investment strategies to potentially increase returns.

Each option comes with trade-offs that have made reform politically difficult, despite overwhelming public support for the program.

A 2024 NIRS survey found over 90% of Americans — across party lines — support Social Security and want lawmakers to strengthen it, not cut benefits. Still, political divisions have stalled decisive action.

Democratic lawmakers have backed proposals to expand benefits by taxing higher incomes, while some Republican proposals focus on limiting the growth of future benefits and encouraging private retirement savings. Without a compromise, experts warn, retirees could face automatic benefit cuts within a decade.
