The caste system in Roshar operates without apology, which makes it useless as political critique.
What matters is the mechanism underneath — brown-eyed people aren't legally barred from power, but they're systematically excluded through something far more durable: the exhaustion of never being given the starting conditions to compete.
Kaladin's arc proves this. He's competent, brave, and tactically sharp — but none of it matters because he arrives to every conflict already depleted.
This is how modern credential-sorting functions. A person from a family of surgeons attends a better school not because they're smarter, but because their parent's credentials unlocked access. That child then outperforms peers from under-resourced schools, gets admitted to an elite university, and the system records this as merit.
Sanderson understands this — he shows us that Kaladin doesn't need oppressors to be kept down. He needs the default settings to stay untouched. That's the insight the work itself doesn't fully grasp: the most stable hierarchies aren't defended violently.
Read Raj Patel's 'A People's History of Civilization' to see how educational access functions as the modern equivalent of Roshar's eye-color caste—inherited, invisible, and defended as meritocratic.
Listen to Sanderson's 'Stormlight Archive Annotations' where he discusses why he made the Alethi caste system eye-based rather than occupational—his reasoning reveals what he was trying to show, and where the argument exceeds his intention.
