is this a thesis statement?

Nicolas Guillen uses the power of symbolism to convey the earnest dream of a man wanting to change the racial disparity between blacks and whites in “Un ***** Que Canta”

Basically, it's a poem about this man wanting peace between black and whites, and a society where they can one day work together. And the poet uses symbolism in his writing to send the message. Does this qualify as a thesis statement?
