What is the author's style in Player Piano by Kurt Vonnegut?

Vonnegut uses language to convey important elements of society. Everyone who has a good job carries the title "Doctor." A real estate agent is a Doctor of Realty. Paul is a Doctor of Engineering. The title doctor is so overused that it almost becomes meaningless, as Haycox points out when he says that he only considers physicians, dentists, and veterinarians to be real doctors.
