Overfunded? My fat ass they were overfunded. That's what the bloated CEO's who wanted to make millions instead of hundreds of thousands want you to think.
I'm glad for you that you've done better with a 401K than with a traditional pension, but that's not the case for millions of Americans. In fact, many respected economists feel that Americans have been SCAMMED with the fees on 401Ks and that converting to private plans was just another way to funnel money to bankers. Most people with 401Ks do not have enough money to retire with...and never will.
