Let me phrase the question differently: How much money is enough if you already have $100M and to gain more, you have to manipulate and cheat? But even without changing the question, $100M invested in a very low risk manner will generate considerable cash flow (if you regularly take some profits). So without even spending your "savings", you can live very comfortably. However, a special thing happens when you are high net worth. You suddenly have a lot of lenders begging to loan you money at very low interest rates. They need a place to put money, and they know you have assets to cover any loan they might give you. So you, the wealthy individual with $100M in assets, CAN still go buy nice stuff even if your cash flow from your investments isn't huge. Honestly, unless you just need to show people how much money you can drop because you're so rich you don't care, you don't actually have to spend any of your money to live bigly.
