I can envision a decent proportion of men, at least myself and a few I know, who would find it preferable to have a redundant source of income in the household.
Even if a woman ends up becoming a non income earning partner temporarily or permanently, having one who is capable of earning more can be a desirable trait for multiple reasons.
Higher IQs are correlated with higher incomes, too: https://www.sciencedaily.com/releases/2023/02/230208125113.h...
Anecdata source of one - but most of my friends from college who could've ended up with many many women ended up with women that had super rich parents, and most of the women that everyone was crazy about ended up with men with rich parents.
None of them claim to have married for money - but from the outside - the odds seem to be that at least some of them probably did.
