When the richest 85 individuals in the world own as much as the poorest 3 billion people, one must ask about equity and social justice. Yet, the problem is not just individual, but also systemic. Just as nations have developed poverty lines to identify people who need help, so too, as this book argues, we need a measure of relative wealth that can guide policy makers, governments, development specialists, and economists. Approaching the question through theological, ethical, and economic analysis, the book probes the dynamics of wealth creation, the effectiveness of national and international policies, and the underlying questions of poverty, wealth, and widening economic disparities.
