You, I mean you personally, cannot generate a billion dollars. Nobody can. I dare you to try. Try to think of a way to make a billion dollars, without already having several hundred million dollars via generational wealth.
You can't generate a billion dollars, but you can find people to generate a billion dollars for you, and then instead of allowing them to share in that billion dollars, you just underpay them. You convince them (by deceit) that $100,000 is a pretty good salary, while you pocket $999,900,000. You tell the government that paying taxes would "significantly harm your business opportunities," so you pay $0 in taxes.
That's how you make a billion dollars. Cheating. Lying. And hoarding. Think twice before you say "not your money" again.
