many men do not choose wives who can have an equal partnership with them
'Equal' would fall outside of the comfort zone, it's too close to the point where she could actually better him in some way and that would make him feel very threatened. Better to keep her as subordinated as possible...
Many career women won't want to hear this but for many of these men who are very career driven/high flying careers, they actually match much better with women for whom career is NOT such a high priority, or women who have careers that are less demanding. Especially if there are children involved.
Two headstrong people both obsessed with their own time-consuming careers, while juggling children and household management is a recipe for a high stress, unhappy environment (and in many cases, divorce).
Despite having some common interests, two people like this will most of the time be simply incompatible in the long term as a family unit.
There's an air of snobbishness in some posts, looking down on women who are less career obsessed as being somehow lesser than women with so-called high flying careers. These men certainly aren't "marrying down". These other women may have a whole range of other qualities that make them more attractive e.g. want to prioritise spending more quality time with future kids, less uptight, or are interesting in other ways. And who's to say that your career in finance for example, is of more value than that of a nurse who is helping save lives?? Just because one career earns a lot more doesn't make it more valuable. 
Yes, some men may be seeking women with less demanding careers due to their own insecurities, but a lot of the time, as men are very rational creatures, they've wisely figured out that marrying their female equivalent is simply unlikely to lead to a long term happy marriage/family.
