Currently 15.3% of our paycheck is going towards Social Security/Medicaid through the FICA tax (remember that employees only pay half that amount as their employers pay the other half).
So bring that down for everybody to a more reasonable percentage.
Bear in mind, though, that there is also a cap on the benefit amount when drawing. If the high earners pay SS on every dollar earned, it would be logically fair that their earned benefit would increase accordingly.
So, we’d be insolvent then, too.
