I think I phrased myself badly.
Many men (my impression) think women overrate their looks. If a woman is of average attractiveness, I think she generally knows it. But, with caveats. Her impression of herself takes a few years to develop and is out of date (beautiful 21 year old women might desperately try to impress you, thrity year old women generally know better). Also, she will see an average man as below average.
This leads to average women often wondering where the decent men are and average men struggling to get a woman. The difference in these complaints is key, men have little problems finding a woman they find a potentially suitable partner, women often do.
This suited in in CA, as there were plenty of women who would not have thought of themselves as having high standards being left unable to find a decent man.
Personally, I think there are very good reasons for women to have this skew in their perceptions. It is almost certainly far safer. But, it does mean they are in a position of finding the opposite sex less attractive than they would otherwise, and a situation where it is very easy for a minority to men to choose a partner and difficult for most men to find one happy to be with them.
Obviously, I am talking about human relationships like commodities. These are huge generalisations.
