MacKenzie Scott actually helped found Amazon, she married Bezos before Amazon even existed and literally worked on it with him from the very beginning. The whole idea that she married into wealth or "got it from the divorce" reeks of sexism.
She's also rapidly giving away her money with no strings attached, and she's supporting underserved communities all over the US. The HBCU in my city got a massive grant from her that's totally transformed what it will be capable of, for example. I just don't get why you're choosing this person to rag on out of all the truly vile billionaires out there
