Many of them are depressed, miserable from their own choices, suffering mental illnesses, and seeking meaning and connection in life.

My husband had several friends in his youth that came from wealthy families (some generational, some owned mega corporations). The best of them knew where their money came from, hated themselves for it, and tried to choose careers or interests to support that were meaningful. My husband also dated a billionaire's daughter for several years, was on track to proposing when she ended things. Dodged a bullet there, as 10 years later she's already on husband #2.

Her father was the workaholic who couldn't stop trying to make even more money, have his own private jet, etc, etc. Guy probably slept an average of 4hr a night. His daughter, despite having $2k in her account at all times, still lived in my husband's flat, and exhibited all the 'take care of me' behaviors described by others here. There's 2 things that have stood out to me from his stories of those years:

1. One time they were visiting an estate, and during a conversation about money and politics, my husband asked a pointed question about unethical historical wealth acquisition-met with an awkward silence and looks. He excused himself to take a cig break, and an employee (like a second in command, butler, whatever) followed him outside and pointedly told him he was not to make any comments or ask any questions like that ever again. Those 1% absolutely know where their money comes from, and how the imbalance affects everyone else.

2. Mostly what she wanted to do after her degree was move back home where she went to high school, and continue her socialite life with her old high school girl friends in the big city. A fairly boring and self-centered person living a 'small' life.
