A Dream Deferred

I feel that this relates to the Harlem Renaissance. It describes the way African Americans feel about their dreams and their lifestyle. That the white people are holding them back from everything they have, until its gone. "Does it stink like rotten meat? Or crust and sugar over-- like a syrupy sweet?" This meaning their dream is like a sweet, something they can't wait to taste. As time goes by though the sweet soon becomes old and crust over, like their dream, dying because it's been too long, and they have finally lost hope.
