Give the people what they want, good and hard

As HL Mencken once said.  The Democrats want to tax the rich, how about something like this: 90% tax on contractural compensation in excess or likely to be in excess of $500,000 for a finite deliverable like an athletic season, a concert tour, motion picture, a book or a season of television programs.  At some point, you have made enough money.   And repeal the Eisenhower tax cuts!
