Naomi Wolf made a very compelling argument in her recent book, "The End of America: Letter of Warning To A Young Patriot" (2007).
Yet, Gross gave us a powerhouse of a predecessor book in the early 1980s with this volume.
You can google around and find excerpts of this book.
The exceptional virtue of Gross' book is that he gives us historical patterns of shifts into authoritarian political regimes.
Sad irony that the book is out of print.
