Excerpt: The Obama administration is looking for ways to make 401(k) and other defined-contribution plans more like those rapidly disappearing defined-benefit plans, which guarantee retirees a pension for life. One idea under consideration is to encourage or require employers to offer annuities or other 'lifetime-income products' as an option in their 401(k) plans. Some folks, intentionally or not, are confusing this idea with a more radical concept to create guaranteed retirement accounts, which would give the government a far greater role in retirement savings.
