Why are there recurring themes of dystopia in this book and other books, too?
One of the primary themes of Philip K. Dick's Do Androids Dream of Electric Sheep? is the nature of the post-apocalyptic world and its terrible hardships--kind of a utopia in reverse. In Do Androids, Earth has become a place where only the poor and unhealthy live; the goal for most humans is to move to colonies in space where they live the good life with robots to do their physical chores. Earth, then has been reduced to a wasteland, where lawlessness prevails. Dick's view of the future is different than many others that are specifically post-apocalyptic. In many stories and films, such as Harlan Ellison's "A Boy and His Dog" or the Mad Max movies, dystopia reigns--but with always a hope of regaining a utopian world. In Do Androids, the good life does exist--just not on Earth. Higher technology, instead of being reduced to ashes, has supplanted human values, and the world has become an ultra-capitalistic place where only the super-rich can escape.
