Maybe Surely I am naive about this, but I was astounded by the fees that Glass and Reich are said to command in this post. Ned Rorem used to be considered outrageous for insisting on a fee to attend performances of his music, but the scale of the fees quoted is quite a different matter.
George Rochberg used to tell us that, “If money corrupts, you [composers] are incorruptible.” I am not saying Glass and Reich are corrupt! Nor am I saying that their fees are undeserved. But there does seem to be less of a distance between them and $$ than is the case for many composers, including some pretty famous ones.
