The Paycheck Argument

It usually arrives in one sentence. I earn more, so it makes sense that you do more at home. Sometimes it is said out loud. More often it is simply how the household runs, and nobody remembers agreeing to it.

The argument sounds reasonable, which is why it lasts. It borrows the logic of a trade: one person brings in money, the other brings in labor, and the two even out. I want to look at what it assumes, and at what happens in households that actually run on it.

Where it comes from

The idea has a respectable history. Economists have long described couples as small firms that divide work by comparative advantage. If one partner earns more per hour, the household as a whole may be better off if that partner works more paid hours and the other covers more of the home.

As a description of some couples' choices, that can be accurate. As a rule for fairness, it has three problems.

What it assumes

The first assumption is that the trade is between equal amounts of work. It often isn't. In the dual-earner couples I interview, the lower earner is usually also employed, often full time. The argument then stops being about splitting a load and becomes a reason for one person to carry two.

The second assumption is that money and housework convert into each other at a fixed rate. The research suggests they don't. In 2003, Michael Bittman, Paula England and colleagues published a study in the American Journal of Sociology asking when gender trumps money. Using Australian and American data, they found that women's housework fell as their share of the couple's earnings rose toward parity. Beyond that point, in some of the data, the pattern turned more traditional. The interpretation has been argued over since. But if the paycheck argument were the real rule, a woman who out-earned her husband would do less at home. In much of that data, she didn't.

So the argument tends to run one way. It is used when the man earns more. It goes quiet when she does.

The third assumption is that housework is a set of hours. Much of it is a set of responsibilities, the noticing and planning and remembering I wrote about in What Is the Mental Load? A salary can pay for a cleaner. It doesn't decide who finds the cleaner, briefs her, and notices when the bathroom is being skipped.

What it does to satisfaction

A long tradition in social psychology, usually called equity theory, holds that people are most satisfied in relationships where what they give and what they get feel roughly balanced. The word that matters is feel. The balance is judged by the people inside it.

That is where the paycheck argument tends to fail. Women in these arrangements rarely object to the principle in the abstract. What they object to is evenings. He comes home and his workday is over. She comes home and hers continues. Shira Offer's 2014 study of dual-earner parents found that mothers did somewhat more of the mental work of family life than fathers, and that thinking about family matters was linked to stress and negative emotion for mothers but not for fathers. An arrangement that looks balanced on paper can still feel lopsided.

I hear a version of this in almost every interview on the subject. I don't mind that he earns more. I mind that he gets to stop.

A principle and an arrangement

A principle can sound fair and still produce an arrangement that works badly. The test of an arrangement is simpler. Do both people get roughly the same amount of time off, and do both carry some of the thinking?

Couples who pass that test often have unequal incomes. They make it work by talking about the whole week, paid and unpaid, instead of swapping one kind of work for the other. The higher earner may do less of the daily housework and still own something completely, from planning to follow-up: the finances, the car, the children's sport. A whole domain the other person never has to think about.

That is a trade, and it can be a good one. The paycheck argument, as it is usually used, ends the conversation instead of starting one.

If you are on the receiving end of it, the most useful reply I've heard is a question. When I earn more, will you do more at home? The answer tells you whether the argument was ever about money. I looked at the same logic from another side in The Provider Problem.
