How do Langston Hughes' poems embrace/define American identity? What different tones do you hear in his poems?

Oh my gosh. I love how he words things. I believe he knew exactly what he was talking about when it came to America and how people acted towards each other in those times. People were treated like animals to work hence "Pack-horse." Or that they weren't good enough to be seen in a good light to the rest of the world. Ah I love Langson Hughes. He's inspired some of my own poems.
