I'm unsure of how to rate this book. The idea is great; the execution, as far as I know, was based on I-Ching readings, so even Phillip K. Dick forced himself to accept the path the story followed by consulting it, and it's noticeable.
Something I liked was the way the populace was minimized, conquered. A thought hard to grasp, since murricans are so full of themselves. Another thing was the superiority of the winners, the closed-mind they all share. Relatable to these days as well.
