 But a major motivation for thinking happiness the wrong object of policy is that neither happiness nor well-being are the appropriate focus of a theory of justice. What justice requires of society, on this view, is not that it make us happy; we do not have a right to be happy. Rather, justice demands only that each has sufficient opportunity (in the form of resources or capabilities, say) to achieve a good life, or that each gets a fair share of the benefits of social cooperation. However plausible such points may be, it is not clear how far they apply to many proposals for happiness-based policy, save the strongest claims that happiness should be the sole aim of policy: many policy decisions are not primarily concerned with questions of social justice, nor with constitutional fundamentals, the focus of some theories of justice. Happiness could be a poor candidate for the “currency” of justice, yet still remain a major policy concern. Indeed, the chief target of happiness policy advocates has been, not theories of justice, but governments’ overwhelming emphasis on promoting GDP and other indices of economic growth. This is not, in the main, a debate about justice, and as of yet the philosophical literature has not extensively engaged with it.
