When the people who work for the $billionaire stop working for him, he fails. Why? He doesn't have enough practical experience doing things for himself to know how to do them... because he has had others do the things for him.
in a way this is true but also billionaires hire people because they are too busy to do everything they have to do all at once. some people who had started as poor climbed their way up and so they have learned how to do practical things and was able to develop skills before they atarted their company and became successful
of course rich people who were born into wealth is a different story because mostly they are the ones who can not do whatever it is that is needed to do i know so many rich people who are too dependent on their money and you know they can never survive a day without it even the simple life tasks like laundry is given for other people to do
i am glad that i at least had to fight my way through life so i am not left clueless
