In 1980 a Benefits Consultant Read a Subsection. You Retired on It.

In 1980, a benefits consultant named Ted Benna was working through the Revenue Act of 1978, looking for a way to restructure a bank client’s cash bonus plan.

He stopped on a short provision tucked into the law: section 401, paragraph k. It had been written to settle a narrow technical question about profit-sharing plans that let employees take cash instead of a deferral. It was not written to replace the American pension, and nobody in Congress had suggested that it might.

Benna read it and concluded it permitted something nobody had built yet: a plan where ordinary employees could defer part of their own salary before tax, with the company adding a match on top. He built one for his own employer, The Johnson Companies, in Pennsylvania.

He is now widely called the father of the 401(k), a title he accepts. He has also said, more than once, that he created a monster — that he meant to turn spenders into savers, and what he got was a system layered with hidden fees and salary reductions that enriched the financial industry more reliably than it enriched the saver.

Both of those statements are true, and the gap between them is the subject of this piece.

What the pension was actually doing

To see what changed, you have to be clear about what a traditional pension did — and it was not simply “paid you money.”

A pension promised a specific number, every month, until you died. To make that promise, somebody had to solve two problems that are genuinely difficult. The first is how long you are going to live, which nobody knows. The second is what markets will do over the thirty years in between, which nobody knows either.

Under a pension, both of those unknowns sat on the employer’s balance sheet. They were professionally managed, legally enforceable, and not your problem. If you lived to 97, that was the plan’s problem. If the market fell 40 percent the year you turned 66, that was the plan’s problem too.

A 401(k) does not promise a number. It promises a balance. The balance is genuinely yours, which is a real improvement — it is portable, it survives your employer going out of business, and it passes to your family. Those are not small things, and the people who prefer the old arrangement often forget how many pensions were lost when companies failed.

But the two hard problems moved with the balance. They are now sitting on your kitchen table.

Nobody chose this

That is the part worth sitting with. There was no debate in which the country weighed defined-benefit pensions against individual accounts and picked one. There was a subsection, an inventive reading of it, and an accounting reality: a 401(k) match is a known annual expense, while a pension promise is an open-ended liability that has to be carried on the books for decades.

Employers were not villains for preferring the first. They were doing arithmetic. But the cumulative effect of several thousand companies doing that same arithmetic was that the two hardest problems in all of finance — longevity and sequence of returns — were transferred to households that were never given the tools, the training, or so much as a warning that the transfer had occurred.

You are the first full cohort

Here is what makes this a live issue rather than a history lesson.

The earliest 401(k) savers started contributing in their thirties in the early 1980s. They are in their seventies now. Which means the generation retiring today is the first one to go through an entire working life and an entire retirement inside this system.

There is no cohort ahead of you to watch. Your parents retired on a pension and Social Security, or on Social Security alone. The question you are facing — how much can I take out of this pile each year without running out before I die — is a question they were never asked, because somebody else answered it on their behalf.

Every piece of guidance that exists on it, including the famous four percent rule, is a model built from historical data rather than a promise drawn from experience. We think the honest way to say that is out loud.

What it means for a nest egg you can’t replace

If you have somewhere between a modest and a substantial amount in an IRA or a 401(k), assembled over thirty years, and no ability to earn it back, then you are carrying two risks that a pension used to carry for you — and you are carrying them without an actuary, a legal guarantee, or anyone whose job it is to be accountable if the answer turns out wrong.

That is not an argument for fear, and it is certainly not an argument for anything anybody is selling. It is the reason this publication exists, and the reason we are far more interested in not losing a third of it than in finding the next thing that goes up.

One thing to do this week

Do not calculate a withdrawal rate. Do something simpler and more useful first.

Write down what your household actually requires in a month if every optional thing stopped — housing, utilities, food, insurance, medicine, transportation. Just the floor. Then write down what arrives every month regardless of what markets do: Social Security, any pension, any annuity.

The difference between those two numbers is the only part of your life the nest egg is truly being asked to defend. Most people have never separated it from the rest, and seeing it alone on a page changes how the whole pile looks.

Ted Benna found a subsection. The rest of the arrangement, including that difference, got assembled around it by accident.
