John Perkins is a pathological liar.

I listened to a radio interview a few years ago when the book mentioned here first came out.

Perkins said he was always the best liar he knew and was proud of that. He said he has been lying all of his life, was lying when he worked IMF, was lying when he wrote the book and was lying right now. Yes, he said he was lying during the interview. He seemed smug and proud of it.

You can't take anything he says seriously even though he may throw out a fact now and then. Overall, he is making it up and amusing himself bigtime. He has made millions selling books so he seems to have the last laugh, at everyone else's expense.
