John Perkins wrote a book "Confessions of an Economic Hit Man" as a disclosure of US foreign policy to economically destroy underdeveloped countries. Perkins claims that US grants and loans increase economic inequality in recipient countries and help US gain influence using debt as a leverage.
I haven't found enough facts to make a conclusion: is this book fraudulent or Perkins' claims are true. For example, Department of State's press release (clearly interested party though) says that facts on NSA involvement are false: NSA isn't an economic institution to organize such schemes and mentioned countries leaders assassinations can't be explained with economic reasons since those countries loans were minor (compared to total US expenses on loans).
The unspoken aspect of every one of these projects was that they were intended to create large profits for the contractors, and to make a handful of wealthy and influential families in the receiving countries very happy, while assuring the long-term financial dependence and therefore the political loyalty of governments around the world. The larger the loan, the better.
Using a principle of innocence presumption I pose a question in this form: what facts prove truthfulness of Perkins' claim?
