What we have seen happen over the past decade is quite similar what happened in Russia in decades before it: complete dismantling of trust, of the idea of truth, of the idea of honesty or integrity. And in that space of uncertainty, a new sort of ruling class is enabled to control the population.
Anti-vaxxers used to be a tiny minority, and living in a crunchy leftish area, they were concentrated around me, and I got into arguments with them all the time. Now, they are no longer leftists, they are MAHA/MAGA, because their fundamental view of the world is not left/right, it's authority/antiauthority. Vaccines were rejected as much because of the idea of an authority "knowing stuff" as it is about the ickiness of something impure being injected into the body, as much as they love the idea of "everything natural" including "natural" infectious disease.
We've destroyed the idea of expertise and authority based on knowledge that's open to anybody who wants to put in the time to learn, and replaced it with authority that exists merely because it hated the past authority, and became what it hated.
