Any egalitarian books with humor?

I saw a clip of battle droids joking around, even at the expense of getting killed by General grievous. Now imagine those droids but instead they can't be killed cuz they live in a fully egalitarian society, where nobody is superior to anyone in any way. I think that society would be a lot less polite and much more blunt, since there's no fear of violence for just speaking.

Have you read anything like that?
