yah, this is the amazing part. societies are much more resilient than we might otherwise give them credit for. we can endure a lot of suboptimality and hardship, and even reasoning our way into tenacious consent, because the activation energy for change is so high and the final outcome so uncertain. perhaps this is the best we can do--find stable local optima for limited spans of time.
but regardless, being able to uncover poor rationale like tautologies is one effective tool in the toolbox for reshaping political narratives. it's a slog for sure, but you do sometimes see narratives change (covid response being a vivid example). being indenpendently-minded (skeptical) helps a lot too, as you're not personally invested identity-wise in any given narrative, and are willing to change your mind more easily as new information rolls in.
we have hugely invested interests working against such reforms, but some of these will come to pass one day for sure, just because enough people will be fed up and demand it, despite the personal cost[*].
[*]: most people are wholly unsuited for conflict (even the constructive kind) because it's so uncomfortable and risky, and in developed countries as we're constructed, the payoff seems so disporportionate (a lot of gain going to others, a little going to you, but you seemingly taking much of the personal risk).
