Her primary thesis is that not only has aid not helped to end poverty (a view also held by William Easterly: The White Man's Burden and The Elusive Quest for Growth, Peter Bauer, and others) but on balance, aid does more harm than good.
Moyo has a PhD in economics, interestingly obtained under the tutelage of foreign aid advocate, Dr. Paul Collier (The Bottom Billion).
The book is short and quickly glosses over multiple topics. For someone unfamiliar with the history and controversies surrounding foreign aid, this book could be one good place to start --but as a defense of her thesis, it falls short. Her arguments are plausible, especially for someone already skeptical of government intervention into economic affairs. A convincing presentation, however, would require much more empirical data and analysis in order to substantiate the claims.
Wanting to obtain an opposing point of view, I asked my favorite Keynesian for his recommendation--and he sent me the link to Stephen Lewis' segment in the following debate. I highly recommend watching at least the opening statements of this star panel which in addition to Lewis includes Moyo, Collier and Hernando de Soto (The Mystery of Capital).
