By 1995, there were more 401(k)s plans than traditional pension plans. Now there are about twice as many. And they're not working out that well, Robert Hiltonsmith, a policy analyst at the think tank Demos, shows in his paper "The Failure of the 401(k)."
The failure, experts say, basically, is this: The typical worker approaching retirement needs about $250,000 in a 401(k). Most don't come close. The average is closer to $98,000 - only a bit more than a third of the recommended amount.
