A meager 8%. You have betrayed your total ignorance when it comes to anything having to do with money. You have no idea what you’re talking about. The only investment that will give you 8% is an extremely risky one and that’s not an appropriate vehicle for a billion dollars. And you say this in the world wide environment of negative interest rates…
The reason not many rich people lose their money is because becoming rich is hard and you have to be smart to do it. You don’t have to be good or moral but you have to be smart. Even then there’s a ton of washout among new millionaires. But you don’t get to a billion by accident. Look at all the people who make tons of money through some other means than intelligence — lottery winners and football players — they all lose their money even if it’s millions. Sorry bud, the system isn’t rigged. Life is just hard.
