Require 100% of Americans to pay Social Security Tax on 100% of their income.
Why is this important?
Currently those who make less than $200,000 (approx) pay 6-1/2% (approx) on 100% of their income. Those who earn more pay that same tax on only the first $200,000 of their income. Why do the poorest of us pay Social Secuity tax on 100% of our income and the wealthy pay the tax on only a portion of theirs??
