Edward Abbey graduated from the University of New Mexico with a MS in philosophy. His 1959 thesis was titled "Anarchism and the Morality of Violence."
Clearly, many of his books are a reflection of these earlier musings. Good News is his sci-fi expression of anarchism.
In Good News, society has collapsed, particularly in areas that were inhabited by high densities of humans, such as Phoenix, that required extraordinary infusions of energy, particularly west of the 100th meridian. Without energy, there was no water delivery, storage, and irrigation. No modern agriculture. No city infrastructure maintenance. No mega-transportation system.
No centralized government.
Jack Burns is on a mission to be reunited with his son, who he hasn't seen or contacted for over two decades. He travels with his friend, Sam, a Native American with unique powers. He falls into a crowd of anarchists who are fighting against a quasi-military government ruled by "the Chief". The Chief accepts execution and torture as necessary to maintain order. The anarchists want to destroy all records of government.
Abbey has written, "Anarchism is not a romantic fable but the hardheaded realization, based on five thousand years of experience, that we cannot entrust the management of our lives to kings, priests, politicians, generals, and county commissioners." This philosophy is expressed in Ayn Rand style in Good News.
According to Abbey, this potential future is very dark, and humanity collapses as the strong bully the weak. The back cover of this book states "With this boldly satirical imaginary world, Edward Abbey asks us to look around and take stock of what we value before it is too late." I would not categorize this book as "satirical." I would say that this book was Abbey's continued experimentation into ways to express his dissatisfaction with the status quo in the west. After all, "Society is like a stew. If you don't stir it up every once in a while then a layer of scum floats to the top."
And Abbey liked his stew.
