What is the author's style in Wine in the Wilderness by Alice Childress?

The contrast in the speech patterns of the less educated characters with that of the more educated characters is a significant element of the dialogue in this play. The three middle-class characters, Bill, Cynthia, and Sonny-man, demonstrate their higher level of education through their use of vocabulary and their speech patterns. Tommy and Oldtimer, who are not well-educated, have somewhat different vocabulary and speech patterns. Childress ultimately uses this contrast in speech patterns throughout the dialogue to point out the tensions which arise from class differences within the African-American community.
