Internal monolouges enable structural inequalities and broken paradigmes. Memetic constructs form the basis for all societal constructs, so I think maybe you are under selling the importance of thoughts in this case.
Your first sentence is quite a claim. Do you have evidence that this is what enables structural inequalities and broken paradigms? Maybe it would be more reasonable to say such internal monologues help perpetuate these things. It seems to me that the structural inequality comes from first.
