No. They need their delusions. It us a critical part of who they are. It is the skin that keeps the worry out, the spine that keeps them upright. They become the lie, the eternal struggle against truth; you cannot remove it without killing them.

The average person's thinking is generally pretty inflexible. This is a defense mechanism that works more often than not in the long run, at least historically. Trust in government institutions can be pretty hard to erode and doesn't happen overnight. Or even over months. Our media landscape is deeply broken, we live post-truth where different outlets paint drastically different realities, to the point that someone deeply living in one space thinks the other sounds completely insane and vice versa. This is not to say that objective truth no longer exists (or that it was ever very popular in the first place) but is now harder to discern than ever before. People can be very good at hearing only what they want to hear, in the way they want to hear it. Often motivated by fear. And it's now easier and simpler to do than ever before.

It's a shit state of affairs.
