Some years ago, a man won the Illinois lottery, for like $100 million. He drove a trash truck for the city, and they asked him if he was going to quit his job...he said no, he only had two years left until he could get his pension.
If I won $400 million, I'd probably net around $200 million or so after taxes. After tithe (my preacher would be happy to see me that Sunday!) and gifts to my kids, I'd still have about $100 million. That's still an enormous amount of money...invested, I wonder what that would draw in interest? Maybe $8 to $10 million a year? Why, a man could probably live on that.
