It's often said that high status men (managers, businessmen, doctors, lawyers) actually prefer women with a college education or that has worked full time in some sort of higher education field because "low status women" - hairdressers, retail workers, waitresses - are TOO low status for them and could potentially cause a harmful image (eg. Rich doctor with the blonde bimbo). They usually want women with at a college education because they would run around in similar upper middle class social circles.

However, having a more educated woman also leads to more arguments - because she is more knowledgeable and thinks more critically. She won't necessarily be as peaceful and pleasant. Especially if she deals with work stress, she'll have a deeper understanding of the world. Low status workers (generally speaking) are in the "ignorance is bliss" mindset and are happier people in some ways.

If being a pleasant and nice woman is important for a high status man, he's better off with a low status woman instead of a highly educated one that could perhaps understand his work and be a better intellectual companion.
