That guy got it right, I have known some fucked up kids that came from rich families. Lazy bums, alcoholics, drug addicts, gamblers.
My family has a business that I use to work at in the summer time when I was younger. The accountant sent an assistant to catch up on the books. I had to get the guy all the info he requested. When Lunch time came we sat around talking and he told us about another client of the accounting firm that won a big jackpot. The guy thought he could live in his house like nothing had changed. He was bothered by people he knew and people that he did not know and he had to move to a more affluent neighborhood. He was bothered there as well. People even found him at his cottage.
I fucked a coke bitch that descended from a very rich family that invented a method of communication that was a technological advancement for the time. After several generations the family was still wealthy into the 80s. One daughter was an addicted coke fiend. She was potentially a heiress to the family fortune, but the family had cut her off because she might harm herself with the wealth. I also have known some of the members of the family that owns a big chunk of BMW. That family insist that their kids are educated, the kids are funded if they keep getting educated. Some of these people have several PhDs that they have never put to practical use. They use their expanded minds to sit on boards to maintain and enhance their family fortunes.
