USA Election Day: To whom does the writer imagining freedom and justice speak?

Let America Be America Again – Langston Hughes
“…I am the poor white, fooled and pushed apart,
I am the Negro bearing slavery’s scars.
I am the red man driven from the land,
I am the immigrant clutching the hope I seek—
And finding only the same old stupid plan
Of dog eat dog, of mighty crush the weak.
“I am the young man, full of strength and hope,
Tangled in that ancient endless chain
Of profit, power, gain, of grab the land!…
“I am the man who never got ahead,
The poorest worker bartered through the years.
“Yet I’m the one who dreamt our basic dream
In the Old World while still a serf of kings,
Who dreamt a dream so strong, so brave, so true,
That even yet its mighty daring sings
In every brick and stone, in every furrow turned
That’s made America the land it has become…”

“The poem speaks of the American dream that never existed for the lower-class American and the freedom and equality that every immigrant hoped for but never received. In his poem, Hughes represents not only African Americans, but other economically disadvantaged and minority groups as well.”
