I do not think she is an idiot. She just knows a whole lot of things that are not true.
At 29, I recall I had some pretty silly ideas about how the world worked as well.
She has had the entire establishment (as you so astutely note) feeding her nonsense and re-enforcing it, over and over and over.
I am not surprised she is entirely convinced of it. She has been told it is absolutely true by authority figures, for her entire rational, life.
It makes for interesting drama. I wonder if she will ever "red pill". I doubt it. She is too comfortable, he interests are now too completely aligned with maintaining the scam.
+. Also she clearly has gotten a good handler and is adapting very fast. She is a true danger to the future of the county.
