i found the book very upsetting (read it when i was 13)
The fear, i think was from an unconcious realization of the futility of mere existence. NOW I also feel fear at the thought of the control the WTS would excercise in those circumstances.
The picture of those in the know living their own lives and others the electronic druggy reality of physical pleasure, is too like the idea of a "New System" with rulers in Heaven whilst breeder creatures ate fed fucked and dug the soil in the name of the Almighty.
