Social Security began as a Depression-era response to mass poverty among older workers

Social Security was created by the Social Security Act, signed into law by President Franklin D. Roosevelt on August 14, 1935. It was built to solve a specific crisis: during the Great Depression, millions of older Americans had lost their savings, their jobs, or both, and had no way to survive. Before Social Security, elderly people relied almost entirely on their children, charity, or poorhouses. Many had nothing.

The program was designed as a form of insurance, not charity. Workers and employers would both pay into a shared fund during a person's working years. When that person turned 65, became disabled, or died, the fund would pay them or their family a monthly benefit. This was a new idea in America — the first permanent federal program to may provide income based on work history rather than need.

The original 1935 law covered only about 60 percent of the workforce. Farm workers, domestic workers, and the self-employed were excluded, which meant most Black workers, women in household jobs, and rural workers received no protection. These exclusions were deliberate and reflected the politics of the time. Coverage expanded gradually over the following decades, reaching nearly all workers by the 1950s.

Key Takeaways

  • Social Security was created in 1935 to provide income to older workers, disabled people, and survivors of deceased workers who had paid into the system.
  • The program operates as insurance funded by payroll taxes from both workers and employers, not from general tax revenue.
  • Originally, many workers — including farm workers and domestic workers — were excluded from coverage, a gap that was closed over several decades.
  • Social Security has been modified many times since 1935, including changes to the retirement age, the types of benefits paid, and the tax rate.

Why it was called insurance, not welfare

The architects of Social Security were careful to frame it as insurance rather than a handout. Workers paid in; they earned the right to benefits. This framing was important politically — it made the program feel like a contract between worker and government, not charity for the poor. It also meant that benefits were tied to work history and earnings, not to how much money a person had or did not have.

This distinction still shapes how Social Security works today. You do not need to be poor to receive benefits. A wealthy retiree who paid into Social Security for 35 years receives the same benefit formula as a low-wage worker who paid in for the same time. The program does not means-test; it does not ask how much money you have in the bank.

However, the insurance framing also created a permanent tension: Social Security is partly insurance (you get back based on what you paid in) and partly redistribution (lower-wage workers get a higher percentage return on their contributions than higher-wage workers do). This hybrid nature has made the program both popular and controversial since its creation.

How the payroll tax system was set up

Social Security is funded by a payroll tax — a tax on wages that workers and employers both pay. In 1935, the tax was 1 percent on each side (worker and employer), applied to the first $3,000 of annual earnings. That meant a worker earning $3,000 per year paid $30 into Social Security; the employer paid another $30.

The tax rate and the wage cap have changed many times. By 1960, the rate had risen to 3 percent on each side. By 1990, it was 6.2 percent on each side, where it remains today. The wage cap — the maximum amount of earnings subject to the tax — also rises each year with inflation. In 2024, the cap was $168,600, meaning high earners pay the tax only on the first $168,600 of their income.

This payroll tax structure means Social Security is self-funded by workers and employers, not by general income taxes or government appropriations. When you see your pay stub, the line that says "FICA" or "Social Security tax" is your contribution to the system. Your employer contributes an equal amount on your behalf.

What the original law actually covered

The 1935 Social Security Act created three types of benefits: old-age insurance (for workers 65 and older), survivor benefits (for the families of deceased workers), and a separate program called Aid to Dependent Children (for poor families with children). The old-age insurance program was the centerpiece.

The first monthly benefit was paid to Ida May Fuller, a retired legal secretary from Vermont, on January 31, 1940. She had paid $24.75 into the system and received $22.54 per month — a benefit that would pay back her contributions in about 13 months. She lived to be 100 and collected over $22,000 in total benefits, a return that would have been impossible under a pure insurance model.

Disability insurance was not added until 1956, more than 20 years after the program began. Before that, disabled workers had no federal income support unless they were poor enough to may have access to for state welfare programs. The 1956 amendment also lowered the retirement age for women to 62 (men could retire at 62 starting in 1961), though benefits were permanently reduced if claimed before 65.

Why coverage was expanded over time

The original exclusions — farm workers, domestic workers, the self-employed — were not accidental. Southern politicians, who controlled key committees in Congress, wanted to exclude Black workers and women in domestic service. Agricultural employers wanted to avoid payroll taxes. These political interests shaped the law.

But exclusion created its own problems. Uncovered workers aged into poverty with no safety net. Self-employed people and farmers lobbied for inclusion. By 1950, Congress had expanded coverage to include most farm workers and domestic workers, though with lower contribution rates and some gaps that persisted into the 1980s. By 1983, coverage was nearly universal — even federal employees and most state and local government workers were brought into the system.

Each expansion required a change to the law and usually involved raising the payroll tax rate or the wage cap. The 1983 amendments, passed after a commission led by Alan Greenspan warned that the trust fund would run out of money, raised the tax rate and made some benefits taxable for higher-income retirees. These changes bought the system another 30 years of solvency.

How Social Security differs from other countries' systems

Social Security is a pay-as-you-go system, meaning current workers' taxes pay current retirees' benefits. This is different from a funded pension system, where each worker's contributions are invested and set aside for their own retirement. Most other wealthy countries use some combination of both approaches.

The United States also chose to make Social Security a federal program with uniform rules nationwide, rather than allowing states to run their own systems. This meant that a worker who moved from one state to another would not lose credit for their contributions. It also meant that benefit levels and tax rates were the same everywhere, though some states and localities have their own pension systems for public employees.

Another distinctive feature is that Social Security benefits are indexed to inflation. Starting in 1975, benefits automatically increase each year based on the Consumer Price Index. This protects retirees from losing purchasing power over time, a protection that many other countries' systems did not have in their early years.

Major changes made since 1935

Social Security has been amended dozens of times. The most significant changes include the addition of disability benefits (1956), the indexing of benefits to inflation (1975), the taxation of benefits for higher-income retirees (1983), and the gradual increase in the full retirement age from 65 to 67 (phased in between 1983 and 2027).

The 1983 amendments were the most comprehensive overhaul. They raised the payroll tax rate, increased the wage cap, made some benefits subject to income tax, and began gradually raising the full retirement age. These changes were designed to ensure the program's solvency for at least 75 years — a goal that has been partially met, though trustees have warned since 2021 that the trust fund will be depleted around 2033 if no changes are made.

Other changes have been smaller but significant: the elimination of the "earnings test" for people over the full retirement age (they can now earn unlimited income without losing benefits), the addition of Supplemental Security Income for elderly and disabled people with very low incomes (1972), and various adjustments to how benefits are calculated and when they can be claimed.

Frequently Asked Questions

Why did Social Security exclude farm workers and domestic workers in 1935?

Southern politicians and agricultural employers opposed including these workers because most were Black or women in low-wage jobs. Excluding them kept payroll taxes lower for agricultural employers and reduced the number of Black beneficiaries. These exclusions were gradually removed between 1950 and the 1980s as political pressure mounted and the program's solvency improved.

Is Social Security the same as welfare?

No. Social Security is insurance funded by payroll taxes; you receive benefits based on your work history and contributions. Welfare programs like Supplemental Security Income are means-tested — they ask how much money you have. You can be wealthy and receive full Social Security benefits. Welfare requires you to have low income and few assets.

Why does Social Security have a wage cap on taxes?

The wage cap limits the maximum amount of earnings subject to the payroll tax. In 2024, you pay Social Security tax only on the first $168,600 of income. This means high earners pay a smaller percentage of their total income into the system than low-wage workers do. The cap was set in 1935 and has been adjusted for inflation since then.

What happens if Social Security runs out of money?

The trust fund is projected to be depleted around 2033 if no changes are made. At that point, incoming payroll taxes would cover about 80 percent of scheduled benefits. Congress would need to raise taxes, reduce benefits, increase the wage cap, or some combination to restore full solvency. This has happened before — the 1983 amendments prevented a shortfall that was projected for the mid-1980s.

Can Social Security be taken away or eliminated?

Social Security is a federal program created by law, so it can only be changed by Congress. Eliminating it would require new legislation. Modifying it — changing the tax rate, the wage cap, the retirement age, or benefit formulas — also requires Congress to pass a new law. No president or agency can unilaterally end or significantly alter the program.
