The poem "Harlem," by Langston Hughes, suggests that the dreams and hopes for the future of African-Americans are postponed or discouraged.
The author uses expressions such as "a raising in the sun," "like a sore," "rotten meat," "a syrupy sweety," "heavy load" and "explode" so that readers can feel, smell and taste how new dreams and ambitions turn putrid and useless when there are no solutions over the course of time.
