How to Fix the Broken U.S. Retirement-Savings System

It’s hard to imagine a social program more dysfunctional than America’s morass of retirement-saving accounts. It costs hundreds of billions of dollars a year, excludes tens of millions of workers, and fails to ensure a comfortable old age for many who do participate.

The U.S. can do much better, at no extra cost. This won’t be easy, but there are examples to follow — including within the federal government itself.

One telling measure of the current system’s worth is how little real harm its disappearance would do. Employers would be relieved of the costs and regulatory headaches of the 401(k) plans that they administer for employees. Investment managers would lose some of the excessive fees that 401(k) accounts tend to generate — but this would be a benefit for savers. Many workers would hardly notice: By one estimate, almost 90% of tax breaks for retirement savings go to the highest-income 20% of U.S. households, a group that would save anyway.

Still, people are demonstrably bad at handling the complex task of saving enough for retirement on their own. They need help, lest they end up overwhelming the nation’s safety-net programs. So what would a better system look like?
