This article does not provide a statistically significant observation. It seems to read as an envious rant about a few potential bad apples. Just because you are a billionaire doesn’t preclude you from being intelligent and hardworking. Some families don’t get swept up in the wealth and require commitment from their children to make their own money and claim such as the LVMH group family and the Murdochs. Their wealth mostly sitting in startup equity, listed large cap equity and other GDP driving asset classes such as interest bearing instruments. Their children tend to inherit a lot of those genetics and traits. They may not see all the consequences to life themselves but they aren’t necessarily oblivious to them either.
