The Social Security Amendments refer to changes made to the original Social Security Act of 1935, which established a system of old-age benefits for workers. These amendments have been enacted over the years to expand coverage, adjust benefits, and address the needs of different populations, including the disabled and survivors of deceased workers. Key amendments include the 1965 addition of Medicare, which provides health insurance for seniors, and the 1972 introduction of automatic cost-of-living adjustments to benefits. These changes aim to improve the financial security of individuals and adapt the program to the evolving economic landscape.
