From a customer review found at Amazon.Com:
"The meat of this book is not so much the specific proposals that the authors offer. Instead, the real point of this book is: Our nation has undergone three revolutionary transformations -- from colony to independence (1770's to Civil War), from agrarian to early industrial (Civil War to 1930's), and from early industrial to full industrial (Depression to 1970's). We are now in the throes of a fourth revolution. Unlike the previous three revolutions, our political system is not up to the challenge because our two parties, who have a stranglehold on the levers of power, are each controlled by the most extreme elements within their parties -- at a time when we need consensus and cooperation, not extremes. You may disagree with their specific proposals, you cannot disagree with their analysis of the situation."
