<span>In 'I, Too' by Langston Hughes, the speaker refers to 'they' frequently throughout to indication a polarisation between himself and wider 'America', the America that he, too, is a part of. In the last instance of this in the poem, the line is 'They'll see how beautiful I am/And be ashamed-' which implies that the bias held by wider America against him exists only because 'they' have not yet seen him for what he truly is.</span>
