$1.6 trillion in Social Security spending in 2025 has sharpened debate over how to prevent insolvency as lawmakers weigh fixes beyond immediate benefit cuts.
Legal immigration is emerging as one proposed buffer because new workers pay payroll taxes, often claim fewer lifetime benefits, and could ease pressure from falling birth rates and a smaller workforce.
Other options remain politically difficult: lifting the $184,500 payroll-tax cap could extend solvency by 30 years, but analysts still point to tougher choices such as a higher retirement age or lower benefits.
The debate follows warnings that the trust fund could be depleted by late 2032, leaving enough revenue to cover about 78% of benefits unless Congress acts.
