I'm past dating age (and anyway I have a relationship that has survived 20 years), but when I was younger, I never considered what the woman would bring to the relationship financially. I'm very traditional, though, so perhaps this attitude is no longer as common as it was when I was younger.

In popular American culture in our time, there is not an emphasis on what the partner brings to the relationship financially. I also did not think much about my wife's earning power (or at least, not explicitly, although we met in college so there is some same-class-ness happening there).

But I think that is not typical of cultures across space and time. Just ask Jane Austen. :-)

Particularly women evaluating men. In general, women see the ability to protect and provide as desireable qualities in a mate.
