There is a great and very apropos passage by Stravinsky about the content of art that I would have loved to quote here
Perhaps this is it?
"The only twentieth-century composers who became rich did so by composing for the ballet. In his early career Stravinsky wrote for Diaghilev, in his late years for Balanchine. It was the income he received from the repeated performances of these works—as well as from the fees for conducting—that allowed him to die a wealthy man."

White Russian, anyone?
