Pierce's book puts into words what every other developed nation in the world suspects i.e. that, vast swathes of the American public are in effect stupid however the author misses some salient points.
He rightly targets the mind numbing nonsense peddled by the far right wing evangelical creationists who are obviously striving for a collective PhD in stupidity, but fails to articulate why these absurd beliefs have become so entrenched in American society.
No attempt is made to explain why Gerry Falwell, Pat Robinson, Ted Haggard, Jimmy Swaggart, Kent Hovind and the plethora of other frauds and charlatans and their associated rackets are held in such high esteem.
Why, are intellectual dullards (Regan & GW Bush) revered by the right wing and highly educated astute constitutional lawyer like Obama demeaned - is intelligence a "sin"?
It would suggest that there is a large section of the American population which has been failed by an educational system that although operating within the only country on earth which has the separation of church and state written into its constitution, is struggling to counteract belief in supernatural deities.
This book is worth reading mainly because it raises more questions than it answers and should engender within the reader concerns that the nation that put a man on the moon and has greatly contributed to science, literature, art and commerce may now be entering a period of steep decline.
