I think the play offers (white Americans) a different way to look at black Americans For instance, in 'Fences' they see a garbageman, a person they don't really look at, although they see a garbageman every day. By looking at Troy's life, white people find out that the content of this black garbageman's life is affected by the same things- love, honor, beauty, betrayal, duty. Recognizing that these things are as much part of his life as theirs can affect how they think about and deal with black people in their lives.
