In spite of general reductions in government spending, the prime minister has found room in the government’s budget to spend money on a major survey of what makes the British people happy. This will be used, in the prime minister’s own words, to guide government policy towards improvements in general well-being rather than improvements in national income. But is it really true that government policy has always been orientated towards maximising GDP? Is it true that well-being does not increase as income increases? Is it true that more equal societies are happier societies? Can we really improve well-being through workplace legislation? Is it right to orientate government policy towards the single aim of increasing aggregate well-being across society as. a whole? These questions and many more are tackled by some of the leading intellectuals in the field. Overall, this monograph provides a substantial challenge to those who want to put the explicit pursuit of well-being at the heart of government policy.
