As the saying goes, money can't buy happiness. I can't say for sure, but I strongly suspect she has BPD or NPD, and both of these disorders cause intense misery for the person that has them, along with people that have the misfortune to be around them. Her outward persona is overcompensating for the intense void within, self loathing and a feeling of worthlessness. They are miserable, insecure and empty and no amount of money or success changes this. The inability to perceive empathy contributes to repeated failed personal relationships, both romantic and friends/family, and usually they have no idea why, they believe they are completely sane and the whole world has it in for them.
A mostly fair characterization, and the reason why getting angry at crazy chicks is waste of time. They see your anger (so much for lack of empathy), they don't know that they are crazy, they think that you are
They are like automatons with no plan, no pragmatism, no goals other than one: trying to fit in and do whatever they think people expect of them and what would make them cool and popular. Faced with conflicting or changing expectations they simply get frustrated, rarely stop to rethink what they are doing and what it is (if any) that they really want to achieve. (The answer is acceptance, I guess). Showing lack of acceptance to them makes no meaningful difference, it's their baseline existence.
Their nature makes them chameleons, displaying the colors of the society they are in. Have an issue with a crazy chick? Maybe you also have one with her family, neighbors, coworkers, investors... or perhas a whole country which makes it a point to systematically ignore all sorts of craziness in the name of absolute egalitarianism
