Lorraine Hasberry's "A Raisin in the Sun" (1959) predates Martin Luther King, Jr.'s famous "I Have a Dream" speech, given in 1963. Nevertheless, many of the dreams that King referred to are also pursued by the characters of hte play.
King wanted an America where black and white could live together peacefully and coexist in an atmosphere of mutual respect. Certainly, the Younger family hopes for this as they prepare to move to Clybourne Park.
King wanted an American where African-Americans had equal opportunities for advancement. Walter Lee wants to run his own business and Beneatha wants to be a doctor.
The speech is about the pursuit of dignity, as is the play.
