You can’t separate income taxes, social security taxes, and other things. This idea you have of a trust fund is just a joke. We all pay in tons of money.. social security on both the employee and employer side is just one part of the total contribution.. and you can add sales tax, state and local taxes, etc.
We all are mandated to pay for things we don’t get payback on directly. We just have to accept that social security and other entitlement programs can only be based on means-testing, and not linked to individual contributions we have or have not paid. It just doen’t work financially.
I agree - however I support coupling it with a phased-in private accounts program. That way you DO get what you pay in.
