Fundamental - forming a necessary base or core; of central importance.
Just - not based on or behaving according to what is morally right and fair.
A society that is founded on the principle of people being granted special privileges and authority based solely on their birth is fundamentally unjust.
Honestly, Baneblooded women are still placed above Baneless on the social hierarchy, and you’re trying to tell me they are the only ones whose treatment you would consider to be fundamentally unjust?
I feel like you’re underestimating the issue. When conscription teams are dragging people from their homes simply because they wouldn’t be missed, and people have to leave their lands because they can no longer afford it, you’re telling me there isn’t any ‘active oppression’ going on? And considering the war lasted for twelve years, I would assume the starvation goes deeper than “some hunger in some areas.”
Then there are of course the numerous factors that existed before the war.
