the mechanism already exists to do it. They can just cut Social Security benefits on the people who have 401k balances.
There has been chatter about means-testing SS, so you could be quite right.
Correct. Whenever anybody says "Let's means-test SS," They are ripping the 401K money from the hands of everybody who has been sacrificing and saving for their retirement.
Classic FR argument: "Well, the SS money is already gone, and I don't care if you have to work for the rest of your life. Somebody's gotta lose, and it's you. Eff you if you were a sap and saved up."
Watch, we'll see one of these looters in this thread.
