I used to work with people with a similar level of wealth and by and large, they were all a bit unhappy. I felt rather sorry for them
In my youth I spent an afternoon on a millionaire's yacht in the Caribbean, it was so boring and I didn't see anyone particularly enjoying themselves. That is partly why I am socialist, so many people deprived of the most basic things to survive just so these people can be bored and miserable spending all that money.
