What are some of the social critiques in Diplomat of Uram?

One of the books in my uni courses is Diplomat of Uram. I am half-way through the book and it's still not enough to answer some of the questions in my exercises. Is there any social critique in this book??? I can't find any. I was gonna go with the typical "rich people are bad, humble people can be great if given the chance" and all that jazz, but that's not even remotely present in the book. Am I missing something? Is there any critique on modern society in that book?
