Consider the most famous pure dystopian tale of modern times, 1984, by George Orwell (1903-1950), published in 1948 (the same year in which Walden Two was published). I consider it an abominably poor book. It made a big hit (in my opinion) only because it rode the tidal wave of cold war sentiment in the United States.
