How should we split expenses if one of us earns much more?

An equal split can feel reassuringly neutral until one person is left with freedom and the other with constant strain. At the same time, a contribution tied to earnings may awaken fears of dependence, debt or being valued less. The arithmetic carries feelings neither of you may have intended to put there.

Try discussing the lives produced by the arrangement, rather than beginning with who is generous or fair. Can both people participate in decisions? Can either decline a costly preference without embarrassment? Does earning more bring an assumed right to choose how you both live?

The person earning less may also need to resist treating every contribution as proof of independence. You need not pay beyond your capacity to remain an equal partner. Consider what each of you contributes, what each has left to live on, and whether the arrangement supports dignity rather than a permanently renewed contest over worth.

Fairness is not always sameness, and an unequal contribution is not automatically fair either. The question is what responsibilities and opportunities each person has within the whole arrangement.

Earnings are one part. Unpaid care, household work, existing obligations and choices made for the relationship also matter. Discuss expenses you both want separately from preferences one person can comfortably afford and the other cannot. A shared standard of living should not be established by the higher earner and financed through the other's discomfort.

Jing attends to dignity. That becomes practical when both people can say that a cost is too much without having their affection questioned. You could compare possible arrangements and the daily consequences of each rather than assuming there is a universally correct formula. Whatever you choose, agree when to revisit it. A system that once felt balanced may cease to fit after a change in income, health, work or care.

The household announces that everybody will carry an equal weight. One person receives a teacup. The other receives the kitchen. Management congratulates itself on its commitment to equality because both assignments contain crockery.

When the second person objects, management explains that the rule is mathematically elegant. The kitchen remains heavy. A committee is established to investigate the second person's attitude.

I suggest that the committee carry the kitchen for an afternoon. This is the entire training programme. No slides required.

Jang mentions preferences chosen by the higher earner. These can enter the home disguised as universal necessities. Suddenly dinner simply has to take place at the restaurant where the napkins have their own publicist. I recommend asking the napkins whether they would enjoy an occasional picnic. If they refuse, the person who invited them should explain how their appearance fee will be covered.
