I can think of perhaps one situation where a woman marries a man who makes less than her.
That is if she marries for potential. If he has drive and ambition and can surpass her.
A man with drive and ambition is very attractive to a woman.
A woman does not want to win, she wants a winner.
Generally speaking, the more a woman makes her pool of suitors decreases. The more a man makes, the more options he has.
Here is pause for thought for the reality of the marriage game for everyone to ponder, just an example:
if I am a wealthy successful man (aged 40) earning 200k a year and I had a choice between a go getter ball busting career driven women earning 80k a year (aged 35) or a sweeter younger more attractive lady (aged 28) that has job that earns 30k a year.
Who will I go for?
What makes a man attractive for a woman is not what makes a woman attractive for a man.
I know of a lot of couples where the man drinks and due to this the woman is fed up of the him sitting in the pub, not helping with the kids, I could make a big list but all these consequences to alcohol create a lot of arguments the next day! Which can then lead to the failure of a marriage.
I know a few women who still haven’t managed to move out of their inlaws houses and buy their own house after years and years which they really want to do... all because their husbands disposable income is all spent at the pub.
I’m in the midlands and there’s a big pub culture here.
And I'm telling you that there are women out there who certainly DO care about those things. The noble minority you refer to have arrived at their magnanimous state of mind because they have NO choice in the matter. Their hand has been forced through circumstances of their own making. Accordingly, they must either accept a lower status male in order to stave off loneliness, or start buying cats. 😅
