In generations past, that was done by women who were counted as not having a job (despite working longer hours than their husbands, 7 days a week). That doesn't need to be the case -- and in fact, dual-income households can create jobs: cleaners, cooks (delivery drivers etc), and childcare. In my grandma's generation, a woman's household duties also included gardening and preserving foods, and making/repairing clothes -- but those jobs have been outsourced so completely that they're now seen as quirky hobbies.
