Maybe it's the case of natural selection for reasons why some women go for the man with the most resources

Or social economic status for their own survival

Keep in mind historically before the advent of contraception a woman would spend the majority of her twenties and thirties

If not even late teens pregnant so it makes sense she would want a man who could look after her and the family

A woman in that situation would not want to be saddled with a loser or weak man
