This was a famous exchange between Ernest Hemingway and F. Scott Fitzgerald. Fitzgerald said, "You know Ernest, the rich are different from you and me." Hemingway replied, "Yes, they have more money."
The phrase was lifted for the title of a book of anecdotes about rich people that I once saw a stack of on a coffee table at Restoration Hardware. I picked one up and it turned out to be freaking hilarious. I heartily recommend it: http://www.amazon.com/Rich-Are-Different-Priceless-Quotation...
For example, there was the English aristocrat who, when told he could no longer afford to keep three pastry chefs (French, Danish, and one other), said "What? Can't a man have a biscuit when he wants it?"
Then there was Christina Onassis' habit of sending her private jet out to get a twelve-pack of Diet Coke every time she ran out. The pilot was asked why he didn't just bring back a full load. His answer: "Because Madame does not want old Diet Coke."
I could quote another dozen stories from memory and this book has been sitting in storage for like 10 years. A seriously hilarious book.
