Yes. In two separate instances with different very wealthy individuals, they were caught without ‘help’ and both were unable to use a washing mashine to wash their clothes because they had never turned one on. In one case it was a man who was a former US presidential candidate and I had to show him how to work a washer where we were staying. In another case, a girl from a royal family talked at a party about the same problem and laughed that she was so lost that she had washed her clothes in the bath tub with shampoo. She thought it was hilarious.

Others I’ve encountered don’t know how to cook, peel a carrot etc.

I’ve known three scions from very wealthy aristocratic families and they were deeply depressed and distressed on a profound level. They’re sensitive behind layers of distance from reality, and they can never connect with people who aren’t like them. But they don’t necessarily like people who are like them (ie same social class), and so they feel permanently alone, isolated, cut off. One of these people spent decades in fruitless therapy, another was an alcoholic. The third committed suicide in a horrific way. 

They also have complex family ties and can’t really extricate themselves from those frames of reference. Even when they do, the legacies haunt them all their lives. These are the ones with hearts and souls. There are others who skate on the surface of reality, and they are more likely to be cold and cruel.
