What is the author's style in Revolutionary Road by Richard Yates?

Language in Revolutionary Road is standard American English and in most cases the meaning is clear and not obscured by regionalisms or literary construction. There are a few exceptions. Shep Campbell, who briefly becomes April Wheeler's lover, reveals through an internal monologue that his wife's family uses such expressions as "It don't matter none", and that he admires her for overcoming her lower class origins. Although the uniform language is English, class differences in speech are depicted to add dimensionality to characters and to help paint the socioeconomic landscape for the reader.
