What is the theme in Breakfast of Champions by Kurt Vonnegut?

One important theme explored in Breakfast of Champions is the proper role of the artist, a particularly difficult question in a society so adept at transforming art into commodity and so immersed in the consoling fantasies supplied by Washington, Wall Street, and Hollywood. By writing a self-conscious, antinovel Vonnegut hopes to prevent his readers from trying to "live like people invented in story books." It is a reworking of a favorite Vonnegut theme, explicitly stated in the preface that was added to the 1966 reissue of Mother Night: "We are what we pretend to be, so we must be careful about what we pretend to be."
