While I'd love to go more in-depth on why I disagree, that would definitely go into spoiler territory, and given that this is something of a space for reviews, that seems like it wouldn't be very thoughtful, so instead, I'll simply say that I think you're interpreting the text very unfavorably, and that Adastra agrees with you on many of these political points, and Khemia is liable to do the same. I would recommend replaying Adastra and paying closer attention to the portrayal of the parents, as well as of the Triumvirs and Cato, who the game considers symbols of the Adastran political system far more than Amicus, who is, if anything, working to fix a lot of the issues you present of it's feudalist notions. Additionally, I'd point out that of course a political drama is liable to focus on those who have political power. In short, I think you're looking for reasons to be mad, and overlooking a lot of the nuance that the franchise is clearly going for.
