"Having only riches enough to be able to gratify reasonable desires, and yet make their gratifications always a novelty and a pleasure, the family occupied that just mean in life which is so rarely attained, and still more rarely enjoyed without discontent."
--- The Gilded Age / Mark Twain and Charles Dudley Warner
Kurt Vonnegut and novelist Joseph Heller were once at a party hosted by a billionaire hedge-fund manager. Vonnegut pointed out that their wealthy host made more money in one day than Heller ever made from his novel Catch-22.
Heller responded, “Yes, but I have something he will never have: enough.”
