Social Security, which marks its 90th anniversary on August 14, 2025, has evolved significantly from its origins as a Great Depression-era measure to a multi-faceted program. Signed into law by President Franklin D. Roosevelt in 1935, the original Social Security Act was a bold step by the federal government to provide economic security, primarily for retired workers. Initially, it only offered a system of old-age benefits funded by a payroll tax on employees and employers.
Evolution and Key Changes
The original act was limited, excluding large groups of workers such as agricultural and domestic laborers, and did not include health insurance. Over the decades, a series of amendments expanded its reach and scope.
- Survivors and Dependents Benefits (1939): The first major change broadened the program to include benefits for a worker’s spouse, children, and survivors, shifting its focus from an individual retirement plan to a family-based social insurance program.
- Disability Insurance (1956): The Social Security Act was amended to include benefits for workers with disabilities, creating the Disability Insurance (DI) Trust Fund.
- Medicare and Medicaid (1965): These landmark programs were added to the Social Security Act, providing health insurance for the elderly and low-income individuals, respectively.
- Automatic Cost-of-Living Adjustments (COLAs) (1972): This amendment ensured that benefits would automatically rise with inflation, a significant change that protected recipients’ purchasing power.
- Retirement Age Increase (1983): Legislation was passed to gradually increase the full retirement age from 65 to 67 to help address the program’s long-term financial stability.
Social Security’s Role Today
Today, Social Security provides financial security to more than 72 million people, including retirees, survivors, and people with disabilities. It is a vital anti-poverty program that keeps millions of older Americans and children out of poverty. While its funding is often a subject of political debate, the program is largely self-sustaining, funded by a dedicated payroll tax. Employers and employees each contribute 6.2% of wages up to a taxable maximum.
Over its 90-year history, Social Security has remained a fundamental pillar of the nation’s social safety net. Its evolution reflects a long-standing commitment to adapting to the changing needs of the American people, ensuring that the promise of economic security endures for future generations.
