Well, this was discovered long time ago, by Vilfredo Pareto, this is exemplification of his 90/10 rule. Having said that... We should be more honest here when we talk about wealth.
If one asks "how much, say, Elon Musk, is worth" we see some crazy numbers with kirjillions of zeros. But those are not "his" money, this is how much his companies are estimated to have. Yes, he has large personal fortune, but it is nowhere near those huge billions of billions amounts.
Second, staying with Elon example, his companies are paying people and other companies that pay people, so there is huge army of people who have food in the fridge because of Elon Musk (I've seen some estimates around ~1 million people overall). Again, they are nowhere near to be as wealthy as Elon, but still, they have a decent live thanks to his companies.
