Legislators are actively discussing the repeal of the Social Security earnings test, which currently reduces benefits for retirees who earn above certain thresholds before reaching full retirement age.

Proponents argue it encourages continued workforce participation, while critics warn of the significant impact on the trust fund’s long-term solvency.
