From a male perspective, at least in my opinion, most men value a woman’s appearance over everything else. So when a man seeks a mate he’s not thinking about what type of retirement nest egg they are going to build and by and large don’t care that much about the type of job she has. Women on the other hand tend to be more practical. How often do you see younger women with older (20-30 years) financially secure men compared to younger men with older financially secure women? So that’s part of the reason why women don’t typically downgrade (so to speak).
