Female hypergamy has dictated a good portion of female sexual preferences for countless generations: only the most resourceful and strongest men were worth mating with.

However, as time goes by and human civilization evolves, this phenomenon seems to fade away. The gender marriage age gap (the difference between the age of husbands and wives) decreases as a society becomes more developed: wealth and resources, experience and social status made older men more attractive, but now that women can achieve those goals for themselves they pay more attention to younger men. There's still an age gap, but it decreases every year.

In less developed societies (wether it's underdeveloped countries today or first world nations in the past) the lack of safety and a more hostile environment force women to desire the most powerful and resourceful men for protection and survival. But in the modern world this is no longer necessary: that's why the figure of the overly masculine, super manly man who fights and provides is more popular in poor nations than in rich nations.

The richest and supposedly more developed countries are often ridiculed for their men being "too feminine" and "not nearly manly enough". Their society no longer needs that kind of men, so there is little demand by women, which results in little supply by men.

Do women chase the strong, powerful "money and muscle" super man? They did, but as history progressed they realized they didn't need that anymore.

Would women rather have more sensitive, loving partners or Mr. Wreck You In Many Ways, the confident, masculine Alpha guy? As time goes by, the emphasis on masculinity has been reduced (but it's not absent).

This evolution favors monogamy and male opportunities for partnership, as there is no longer a big reason for women to desire the Top Males above everything else.
