Well 401k’s specifically replaced Pensions that were a much better bet for workers and required companies to fund them etc. Now all those other things exist so that people rich enough to leverage them all can minimize their tax burden. They are just Tax Shelters.
Lol, as if pension funds never go insolvent and companies never played games reducing benefits (or other shenanigans so they don’t have to pay out).
At least with a 401k they can’t take the money back once it is deposited.
