Over the holidays, The Washington Post interrupted the good cheer to bring us “a preview of a U.S. without pensions.” Peter Whoriskey tells the story of 998 people who lost pension benefits when the airplane maker McDonnell Douglas closed a plant in Tulsa, Oklahoma, in 1994. It’s a story that features bankruptcies, lost homes and long-deferred retirements. It’s compelling, it’s sad and it’s not a useful guide to the future of American retirement.

It is part of a journalistic genre that laments the decline of the traditional defined-benefit pension and the rise of defined-contribution plans such as 401(k)s. If you want to write an article in that genre, there are four rules that appear to be obligatory.

• First, gloss over how rare defined-benefit pensions really were. Even at the mid-1970s peak of defined-benefit plans, fewer than 40 percent of private-sector workers had them, as Joshua Gotbaum of the Brookings Retirement Security Project noted. Today, decades after the shift to 401(k)s began, 61 percent of private-sector workers are participating in a retirement plan, according to Social Security Administration researchers. The percentage of all workers vested in any kind of retirement plan has risen from 24 in 1979 to 43 in 2012, an Employee Benefit Research Institute study found.

• Second, ignore the advantages that 401(k)s have over the old defined-benefit plans – even when the risks and flaws of the latter are staring you in the face. Referring to the McDonnell Douglas workers, Whoriskey writes, “Because their pension benefits accrued most quickly near retirement age, the pensions they receive are only a small fraction of what they would have had they worked until full eligibility.”

In defined-benefit plans, benefits typically depend both on years worked and final salary. If you lose your job in your 40s, that structure works against you. The connection The Post fails to make is that these workers might well have been better off if the shift toward 401(k)s had happened decades earlier.

• Third, rely on misleading numbers that suggest we are in a “retirement crisis.” Almost half of families have no defined-contribution retirement accounts, The Post says. That’s true, but we’re still making the transition away from defined-benefit accounts. Count all retirement plans, defined-benefit and defined-contribution, and nearly three-quarters of near-retirees have them, said American Enterprise Institute resident scholar Andrew G. Biggs.

• Fourth, never look at data on how retirees are doing overall and how their condition has changed over time, no matter how relevant this information would seem to be to your overall story. The median senior household of 2013 had an income one-third higher than the median senior household of 1989, Biggs has found, even after adjusting for inflation.

Breaking these rules shouldn’t lead you to conclude that our retirement system is perfect. Some people ought to be saving more, and some policies need to be changed.

Too many workers, particularly low-income workers, do not have access to 401(k) plans. It might make sense to let them save money in the Thrift Savings Program for federal employees, as Sen. Marco Rubio has proposed. Social Security should be reformed so that it does less to suppress saving and more to protect the elderly from poverty. A guaranteed minimum benefit above the poverty level could be more than paid for by reducing the growth of benefits for high earners, and lower payroll taxes on older employees can encourage longer working lives.

These are changes that would build on, rather than attempt to reverse, the last few decades of developments in the American retirement system. Those developments, especially the rise of the 401(k), have largely been for the better. Thanks to them, the future of retirement is not going to look like the old age of those McDonnell Douglas workers.
