I am reposting a comment which seems to have vanished in the aether. 

There is another poem by Langston Hughes that comes to my mind, "Let America Be America Again". It begins

Let America be America again.
Let it be the dream it used to be.
Let it be the pioneer on the plain
Seeking a home where he himself is free.

The entire poem is on-line at https://www.poemhunter.com/poem/let-america-be-america-again/ among other places.
