Straight and to the point. This is European colonialism in a microcosm. If the ending takes you by surprise, you weren't paying attention. It's not overt racism that does the real damage to someone's self-worth. It's indifference and self-interest that hold an entire People back from their true potential. Racial slurs and physical violence are certainly abhorrent and hurtful, but a lifetime filled with people taking advantage of you simply because of your situation, combined with others who are either indifferent to that situation or who do only the bare minimum is what can really destroy a soul.
