Should we put the kibosh on 401(k)?

Time Magazine discusses: The one big positive of the 401(k) is that it's portable, while most pensions aren't. But on balance, there's widespread agreement among those who study retirement matters that the 401(k) has so far proved a less-than-adequate replacement for disappearing corporate pensions. "It may be a good tax-free-savings system for wealthy individuals," sums up George Miller, the California Democrat who chairs the Education and Labor Committee and plans to spearhead a re-examination of the 401(k). "It may not be the best retirement-savings system for working families."

That leaves the question of just what the best retirement-savings system for working families might look like. There have been several proposals (including one by Barack Obama during the campaign) to create modestly subsidized, automatic IRAs, at least for the more than 50% of private-sector workers who don't have access even to 401(k)s. Ghilarducci wants more -- a government-run plan, financed in part by the end of the 401(k) tax deduction, that would guarantee a 3% return above inflation. Don't think that's a good deal? Fine. But remember that for most Americans, the 401(k) isn't either.
