It's because the mass majority of smart women with something going for themselves are not going to sign themselves up to be a sidepiece to some entertainer.
If you knew some dime was a massive player, you'd try to wife?
Would some of ya'll try to wife up Megan Thee Stallion knowing you're going to end up in some stories some other rappers going to tell and crack jokes on?
On some "...and her man was on the other side of the room talking to the event coordinator while this was happening

Well, smart women don't want that for themselves either.
One of the baddest women I've ever met in my life worked in tech making bank, has a degree in Math and was actually working on her PhD (edit: checked LinkedIn, said she got her PhD).
Truly one of the planet's best brains/body/face mixtures. She don't run in those entertainment circles (and she has a large network so has the opportunity to). My impression always was she's going to marry someone really smart like herself, and she did.
That's when I realized the average person can land a much better overall woman than most athletes/entertainers if they step themselves up.
