There's no civilzational advancement though if we just allowed women to choose, since they'll all choose the top men and the bottom criminals, meaning the middle majority of men have zero incentize to contribute to the civilization.
Fascism is a system that allows the top 85% of men in terms of "goodness" to get a waifu of their desire, which is the best balance between civilizational advancement and genetic evolution.
Not enough women you say? Fascism's civilizational advancement allows its men to have women of other societies, until fascism's lack of kvetching on genetic research eventually produces alternative solutions.
