IMO, the easiest way to do this is to means test Social Security, more than it already is.
For example, raise the maximum taxable percentage of SS from 85% to 100%. Once that is accomplished, then proceed to actually CUT SS payments to those who have “other” pension plans or IRA/401k distributions.
The sales pitch will be something like: “Those folks have ‘enough,’ so they don’t ‘need’ Social Security.”
Agreed. That is coming. What I have read, and who I have spoken to, leads me to this conclusion: they are going to merge ALL retirements into a sort of Marxist mixer. They will seize your IRA and 401K and give you a "bond", but that will last only a short while. Any hope of getting Social Security, but more importantly if you are old, Medicare, will be DIRECTLY tied to you submitting.
The plan has been in the works for years now, and they are just about ready to spring the trap.
