In college or after establishing a career. They aren’t sitting around searching for a submissive broke woman to take care of. Nor are they particularly worried about a household. These dudes work all day, their wives work all day, and they hire a nanny or au pair to take care of the children during the day. That’s six figure suburban life in America, and it’s super clear KS has no idea.
The market for these videos are largely black men and black women. So right off the bat you aren’t reach many high earners. This is about entertaining men by humiliating/trolling women, and humiliating women who are dumb enough to call this guy for advice. That’s all it is. It has no real value.
One of the biggest points he makes which video after video has shown, is that there are many women that are not on the level of women you are referring to wanting a high earning man. He has women that are at least one of these calling him: Fat, disagreeable, average at best looking, children out of wedlock, etc... turning their nose down on blue collar and average earning men because they overvalue themselves. Also the fact that many of them do not want to work after marriage is a negative since most married women work.
Also a reoccurring theme that answers your question is that you have women that had a guy in college or right out of it and they left them thinking they could do better. Which they did not and the the guy they left went on to bigger and better things. No one is saying men do not get educated women in college to marry, but if they do not after some years at least for some of them the calculus changes in regards to mating choice, which does not mean only wanting a homebody.
