The author of this poem went to great lengths to show his racism. It reminds me of a post, probably on Reddit, of a similar racist nature. Just when it's going in the other direction it's clearer.

The post was by a man, supposedly white, who had to pull his child or children from private school because he could not pay for it. His frustration was based on the fact that his taxes were higher than the school tuition, and that another student at the school, a black student, was having his tuition paid by the government. He implied that he was paying for another person's education, and could not afford his own child's education. He saw the same dichotomy as that expressed in the poem, in the other direction.
