John Perkins is not a talented writer. He’s an even worse human being. I don’t like him. His books, however, are informative, and should be read. Not because they are well-written, not because he deserves praise, but because a lot of what he has to say is true, and it needs to be said.
Perkins worked for the World Bank (directly or indirectly) in international development (which is more like “international economic sabotage”) for years, and his book is a sort of self-aggrandizing accounting of how he ruined thousands if not millions of lives in poor countries in order to make himself and others rich. The book lacks the humility that I would hope to see from someone who has realized the err of his ways. And his subsequent activities (getting rich off this book, and doing ostensibly nothing to help the people he claims he feels bad about immiserating) circumstantially support my conclusion, I believe.
So my advice is to read this book, but not to buy it, at least not new. Check it out from the library, download it, get it at a used book store ($5.87 shipped), do whatever necessary to read it without giving John Perkins so much as a dollar.
