Most women I've known are attracted more to a thick wallet. I've seldom seen one trade down, if you know what I mean. Often I've seen them leave the cute hunk once they get a few years of just getting by and land the ugly engineer. Just sayin'.
You raise a strong point. I think there's a function of age involved, at least in my observations. I have some friends who are DJs, and through them I have been friends with a number of very attractive women. When we became friends, they ranged from late 20's to mid 30's. They were very focused on guys with big pecs and sick abs. I was a little jealous, but hey, they're my friends, and they were having fun so I'm happy for them.
Now, as they're in their mid 30's to early 40's, most not yet having settled down, there is a great deal of reevaluation going on. The party boys they have been with haven't really made much of themselves. Now they're looking for more substance (success is a big part of it, but it's bigger than that).
And here's the part that is a bit painful to see in people I care about: They're realizing they are no longer the hot commodity. Having not spent too much time on their own educations or careers, they are wondering if their window is slipping past. Same can be said of some of the men I've known -- particularly those in young-mans careers (eg: I know some investment bankers).
Here's the truth that runs throughout it all though: The sooner a person comes to terms with reality and accepts themselves for who they are, the happier they are. By miles. The lies are poison.
