I've always scoffed at the idea that some black women can't find black men on their 'level' so they have to turn to white men instead. The reality is most of them marry the first white man who wants them.
Most of these guys are not necessarily into black women it's just a convenient option. They themselves usually can't lock down a comparable white woman so they settle for black.
I've known at least 2 different black women like this. One of them was my ex neighbor. She was a very well dressed and well spoken professional. I don't know her exact profession since she rarely ever spoke to me but it was a corporate job. Her white husband was a cable and satellite installer

with a big white van parked outside their house. Low skill blue collar.
No offense to any of my brothers working as cable installers but chicks like her usually thumb their noses at black men with similar jobs.
The second was an ex coworker at a medical sales company i worked for. She only dated white guys and her boyfriend at the time was a dude who worked back in the warehouse of the same company.
The guy was cool everyone liked him but he was a bum. He had a drinking problem, multiple dui convictions, no car, no house he used to crash on different peoples sofas or was always needing a roommate in his 40's.
Meanwhile the girl was earning about 50k a yr. It's apparent that white guys in similar income brackets are generally not interested in black women.
