Then there is the sequel where the poo people fight back, but they do it in the wrong and bad way which really enforces why we kept them as poo people in the first place! Otherwise it upsets the natural hierarchy and don't you know they just create their own hierarchy that is even worse because it doesn't even acknowledge special people?
Edit: that also makes it praised for it's 'realism'.
We need more works of fantasy about class struggle
EDIT: It's interesting because I think most readers read those stories and imagine themselves as one of the specials, whereas I always imagined being one of the poo people.
what book are you on? i just started book 10. truth be told i like the books a lot and they are absolutely epics with incredible world building especially given how long ago the first was written. having said all that... yah, there's infinitely better stuff written in the past decade
