F. Scott Fitzgerald tells us "the rich are different from you and me" or words to that effect. How? Does richer make them better?

They're not better. They're different. They move in different circles, keep different friends, have different concerns and a different lifestyle that I'll never know. While some pursue more wealth, some do not. They are as susceptible to dissatisfaction as those who have less. Meaning of course that the grass is always greener on the other side. Money can't buy one more minute of life or one more minute of youth for all its other advantages.
