Abstract
In this article, I explore some advantages of viewing well-being in terms of an individual's health status. Principally, I argue that this perspective makes it easier to establish that rich countries at least have an obligation to transfer 1 percent of their GDP to poor countries. If properly targeted at the fundamental determinants of health in developing countries, this transfer would very plausibly yield a disproportionate `bang for the buck' in terms of individual well-being. This helps to explain how the obligation can be both light enough in its burden on the rich to avoid being `too demanding' and yet also bountiful enough in its effects to be worthy of the status of a `minimum obligation'. The advantages I enunciate are particularly relevant to establishing an obligation in the context of a non-ideal theory of international justice, which aims to set interim targets for practical action before an ideal theory has been settled. Key Words: health international justice foreign aid determinants of health non-ideal theory.
