No, that's not how and why it is working. Women tend to marry upwards, because they can. Far more than men, they are the sex that does the choosing. As the choosers, by generally choosing men with better jobs and/or social status than their own, this leaves men for the most part viable marital partners only to women with worse jobs and/or social status than their own. Men, unless up toward the top of the social hierarchy, where they may be entirely oblivious to it, learn this through experience quickly enough. Many more probably want to date and marry women of their own "level" or higher, or do so without regard to social levels at all, than do, but realize it's not likely to work out, or to work for long. Men know that women with better opportunities will generally take them. So they tend to to go where they are wanted rather than waste their time.
