In many ways John Perkins asserts that slavery and imperialism have taken on a new face. That face being large corporations, America, and private organizations giving out loans to developing countries that they can never pay back. The developing countries people, governments, and industries are then under the control of the wealthy and powerful individuals and countries that loaned the money in the first place.
It is an honest reflection on the REALITY of how America has interacted with the world for the past 40 years. And statistics prove that the gap between the rich and the poor has widened since 40 years ago. Hence, Perkin's confessions are a confession to his involvement in widening the gap between the rich and the poor.
He had been writing the book on and off for awhile but in the wake of 9-11, filled with guilt and a conscience telling him to confess how his life and EHM lead directly to the disaster of 9-11 he finally finished his story.
It reads like a spy novel laced with an unadulterated depiction of America's involvement in global capitalism for the last forty years. Everything from George H. Bush's invasion of Panama to loans given to Indonesia to forever keep them in debt to America.
