A few things:
1. Yikes! That is one impenetrable wall of text. My eyes hurt just from looking at it. Please, change the font size and/or add some paragraph breaks.
2. Karma isn't some cosmic retribution system. It doesn't overthrow tyrants. It doesn't punish, it instructs. It is about moral causality, yes, but it's supposed to work by transforming the agent. I don't claim to be an expert on karma (nor do I believe in it), but this is my understanding of it: If you do good acts, you become a good person and your ability to experience happiness increases (maybe people will appreciate you more because of your kindness, or maybe virtue is its own reward). If you do bad acts, you become a bad person and your ability to experience happiness decreases (this might manifest as guilt, shame, an inability to ever fill that black hole of desire in the pit of your stomach, or w/e).
And, of course, karma is also supposed to affect what you will be reborn as (and if you will be reborn at all).
3. Tess seems to be a fan of the Marquis de Sade (IIRC, Juliette Karlsson is named after the character Juliette from the books Justine and Juliette by de Sade), and that makes me think that there won't be any "karmic" comeuppance for the "rich and insane" in the end. If you haven't read Justine, it's basically all about the idea that the pursuit of virtue will only lead to pain and misfortune. Throughout the novel, all good acts are punished and all "evil" acts are rewarded.
While I don't think characters on the good/dom path will be punished just for being good (as long as they're smart about it), I also don't think there will be an ending where the downtrodden masses rise up and overthrow their oppressors once and for all. Or, at least I hope there won't be an ending like that.
