The book is in three parts. Part 1 presents a pluralist analysis of disadvantage, modifying the capability theory of Sen and Nussbaum to produce the 'genuine opportunity for secure functioning' view. This emphasizes risk and insecurity as a central component of disadvantage. Part 2 shows how to identify the least advantaged in society even on a pluralist view. The authors suggest that disadvantage 'clusters' in the sense that some people are disadvantaged in several different respects. Thus identifying the least advantaged is not as problematic as it appears to be. Conversely, a society which has 'declustered disadvantaged'--in the sense that no group lacks secure functioning on a range of functionings--has made considerable progress in the direction of equality. Part 3 explores how to decluster disadvantage, by paying special attention to 'corrosive disadvantages'--those disadvantages which cause further disadvantages--and 'fertile functionings'--those which are likely to secure other functionings.
In sum this books presents a refreshing new analysis of disadvantage, and puts forward proposals to help governments improve the lives of the least advantaged in their societies, thereby moving in the direction of equality.
