Forgive me for disagreeing, but I have a different take on this speech. Although he is unable to think out of the context of inflated self-importance (and of course, its flip side, despair) and thus is completely incapable of true irony, I have no doubt that Joe is sincere in his desire to be of service.
In my judgment, there's nothing wrong with these remarks, though, or course, they are hardly earth shaking or deeply insightful.
Just my take.
