This is a delightful book that addresses a very complex subject and offers a well-informed and analytic treatment. The work covers a lot of ground and does so with an easy flow of writing and clarity of thinking. The work makes a unique contribution in outlining the complex and nuanced nature of the “poor,” how this subject has been addressed, and what options are fruitful to explore in the coming decades. The work is well-informed and draws on reasoned interpretation and sound connection to the literature. This is not easily accomplished, but the authors have achieved this with a respect for the literature.
