I don’t see a strawman there. You seem to be assuming that women were originally forced to start working because suddenly dual incomes became necessary. In reality many women and men prefer the satisfaction of being able to exercise skills and perform work beyond housekeeping. Saying one income should be enough ignores the fact that in many couples, neither partner wants to have no career.

If nothing else, it’s not pragmatic to be the one that doesn’t work. Divorce or the death of a spouse can happen. If a person who never worked is suddenly left to fend for themselves, they find themselves in a job market with no experience or job history.

Once you have both people in a household wanting to work, and the resulting higher spending capacity of double incomes, inflation starts to take effect and drag everyone else along.
