Many years ago at a tech conference in Arizona, I was seated next to a billionaire. He had started a shoe company, very successful, sold it. I tried to have a conversation, but he mostly ignored me. He said something I remembered. You can't get by on less than $20 million a year. I looked to see if he was joking. He wasn't. I said you know that's not true. I live quite well, but I don't even spend $1 million a year (an understatement, I probably didn't spend $100K a year). I said there are lots of people who get by on $30K a year (it was a long time ago). He didn't say another word the whole meal.#
