To keep Social Security solvent .
Why is this important?
A simple first step to keeping Social Security solvent is to tax ALL income. Millionaires / billionaires have been getting a tax break for decades by only paying Social Security tax on the first $110,000 of their incomes (which has slowly increased over time). So someone making $1 million a year pays on only $110,000; leaving $890,000 untaxed. Over time that adds up to lots of extra capital ! Why is this allowed ? Social security was never intended as a retirement instrument for the rich .... time to reverse this tax break !
