What a strange observation you have made, you've picked a few bad examples out of many millionaires and billionaires, then tried to project your own opinions on to them. Elon might be the richest man in the world, but this only makes him the most visible in the headlines and he is a huge oddball when it comes to the mega rich. You'd be surprised at how down to earth most of them actually are because they have complete freedom in life. You'll find people with mental health issues in all walks of life and people going through calamities like divorce or losing a loved one can go off the rails a bit, yet they get to experience the best of everything in life. Try to avoid defining everyone in the "rich" bracket by these tech billionaires you constantly see in the news.
