This article provides a qualified defence of economic indicators of hu
man well being. Purchasing power obviously matters as a prerequisite f
or obtaining basic needs; abundant examples of human behaviour even in
the richest countries in the world suggest that it matters for many o
ther reasons, as well. Despite the shortcomings of indicators like GDP
and GNP, richer nations (like richer individuals) have options that a
re simply not available to poorer ones. A particularly serious limitat
ion of such indicators arises from their failure to take into account
the distribution of income and wealth, both within and among nations.
Higher income does not automatically lead to increased well being, but
extreme caution is in order about attempts to dismiss its contributio
n, or to pathologize certain forms of consumption. While arguing the m
erits of a lifestyle less organized around consumption, proponents of
sustainable development must acknowledge the strength of the evidence
that money matters.
