In my experience, at this point it's less True Believer NPCs and more people who are in deep denial because they have a tiny, but non-zero, chance of suddenly dying at any point for the rest of their lives because they trusted the system. This is a very hard pill to swallow, and it's easier to just pretend everything is fine than confront the truth.

I mean, technically we all have a tiny but non-zero chance of dying suddenly at any point, but you know what I mean.
