I think Musk is a better example. Money is just a medium for him to change the world for the better. I'm sure being rich makes Musk happy, only because it enables him to make a difference.
But then those same empathetic people will speculate, "I can tell <famous person> is totally unhappy -- idiot!"
Personally I think these types of people are abnormal and their "success" isn't something I aspire to.
