Its hard to feel too much sympathy for such women when the obvious answer would be to lower their standards somewhat. The exclusion seems to be down to their own choices.
1. High status men have access to a lot of attractive women. With the way men's biology is wired, it wouldn't be surprising that they would choose an attractive, relatively lower status woman over a highly accomplished but not that attractive one.
2. High status men often have stressful work lives. They would probably prefer a partner that makes them feel relaxed at home. High status women usually have careers themselves so it would be difficult to provide this need.
For that matter, you don't have to be with anybody at all, which may be why you see women rather be alone than follow parent's suggestion!
