This, as well as the others before it, is a phrase that should never be said about a student. No student is ever doomed to failure. Even if their home life is not perfect, they can still excel. If teachers have this mindset, then of course their students will not do well. They need to provide an environment for students where phrases like this do not exist. Aaron was demonstrating great literacy skills that his teacher did not even realize he had, so it is not fair to say that this home environment he was in makes him doomed to failure.
