When all of this analysis goes no further than the story itself, and doesn't take even a step into our own world, because the entire species just loves serving and is right where it should be serving us? Yeah, that'd be superficial.
Take Hermione's activism, for example. Her original activism fails to respect the viewpoint of those she wants to help; she grows to be helpful in a way that's more respectful. That's superficial analysis, yes-- it's literally just what the story presents to you. Dig just an inch more and you notice that the activism the book presents as bad and disrespectful is... activism that aims at systemic change. Systemic change is portrayed as naive, laughable, doomed to fail, and not in the interest of the workers who just love to work. The activism that really works, and is respectful, is portrayed as... ameliorating the conditions within the existing system, rather than challenging or changing it.
The irony of saying this, and then accusing someone else of poisoning the well, ain't lost.
Hypocrisy.
