The thing about money - the only thing money is actually good for is: manipulating the behavior of humans.

You can’t eat it, but you can get people to give you food in exchange for it. Money doesn’t grow food, but it does get people to do the work of growing and harvesting and shipping and preparing food…

Money doesn’t build your house, but it does get people to build a house for you. It doesn’t make electricity, but it does get people to build and operate electrical generation systems…

So, what are Billionaires? They’re actually just power-centers of people manipulation by money.
