Who is Michael Milken from The Predators' Ball and what is their importance?

Milken works at the Wall Street firm of Drexel Firestone, as the book opens. He spends two hours commuting to work via bus from his Cherry Hill, New Jersey home. He does so to avoid having to talk to other Wall Street people that he might meet. Milken is not a social climber. He had been raised in a middle class Jewish home and did not care what kind of car he drove or what kind of clothes he wore.
