Sen. Bernie Sanders (I-Vt.) called for the elimination of the Social Security payroll tax cap following Elon Musk's rise to trillionaire status.

The proposal targets a systemic gap in the U.S. tax code that allows the wealthiest individuals to pay a lower effective tax rate on their total income than middle-class workers. With the program facing a projected insolvency date in 2035 [3], Sanders said that capturing these missing funds is essential for the system's survival.

Under current law, the Social Security payroll tax applies only to the first $184,500 of an individual's earnings [2]. This means that a worker earning a middle-class salary pays the tax on 100 percent of their income, while a billionaire only pays on a small fraction of their wealth.

Sanders highlighted this disparity by pointing to Musk, whose net worth has reached $1.1 trillion [1]. He said that despite this immense wealth, the entrepreneur's contribution to the Social Security fund is limited by the same cap that affects average earners.

"Today, Elon Musk, a trillionaire, pays the same amount into Social Security as someone making $184,500," Sanders said [0].

The senator described the current structure of the payroll tax as an "absurdity" [0]. He said that removing the cap or implementing a wealth tax would generate the revenue required to sustain benefits for future generations.

Critics of such measures often argue that Social Security is a benefit program based on contributions rather than a general tax, but Sanders said that the current cap disproportionately protects the ultra-wealthy at the expense of the program's long-term health.

"Today, Elon Musk, a trillionaire, pays the same amount into Social Security as someone making $184,500."

This debate centers on the fundamental design of the U.S. Social Security system, which was originally built on a payroll tax model rather than a wealth-based model. By highlighting the contrast between a trillionaire's contributions and the program's looming 2035 insolvency, Sanders is attempting to shift the policy conversation from benefit cuts to revenue expansion through the taxation of high-net-worth individuals.
