Why? You saw the house, you saw the neighborhood....everything in the video makes it clear that she's very successful and well educated. Why you thought that was unlikely...I'll let other people speculate on that lol. Her being successful and smart has nothing to do with her also being a piece of shyt.
When I was a kid my parents thought it would instill a good work ethic in me by forcing me and my siblings to do yard work at their friends houses for money. Not a lot of money, just a few bucks to shovel snow or rake leaves. My parents were well off at the time but weren't rich. One time we went to one of their friends houses who was a rich black woman in her 50s. Not married, no kids. She later committed suicide btw. But I remember she wouldn't look us in the eye, treated us like short bus kids, told us not to sit on any of her furniture while we helped move some stuff into her basement. High black society, graduate degree, very light skinned, prominent family. Her nieces were at the house. They were close to my age and I remember this lady saying "don't talk to them, go to your room." Like we were some type of plague.
I have a graduate degree, I'm not categorically shytting on well educated black people. I know plenty who are just normal people. But I also have been around more than enough bougie blacks. They look and act the exact same, it's really disgusting. I got so many stories about them lol.
