Social Security was created in 1935 to provide income security for older people by pooling resources through mandatory payroll taxes. It aims to prevent financial disaster for retirees and ensure basic protection for those in need. Social Security benefits individuals across their lifetime through retirement benefits, disability insurance, and survivor benefits. It is the primary income source for many retirees, with over 50% of beneficiaries relying on it for at least half their income. While it faces funding challenges, proposals to reform it focus on options like raising taxes, adjusting eligibility ages, or reducing benefits.
