I assume you mean Social Security. Over the last 30 years upper-to-high incomes have skyrocketed while the legal SSA-taxable income cap remains at $118,500.[1]
Reports of Social Security's imminent death are greatly exaggerated, and more often than not a part of a classic Neoliberal (1940s+ Neoliberalism, not the Clintonian/New Democrat brand) "starve-the-beast" plan to convince young people that the program is unsustainable and should be gutted so people can save a measly few percentage points of take-home income. It is a generations-long propaganda tactic that makes sense if you don't think too hard but the simple fact is that raising the cap modestly will keep Social Security solvent for a very long time.
