particular conception of human beings that the sufficiency perspective I am outlining rejects (Alexander, 2012d). If it were true that happiness and fulfilment consisted in the consumption and accumulation of ever more material things, then, admittedly, a sufficiency economy would seem to be inconsistent with 'the good life.' But that is far too narrow a conception of the good life and it is based on a misunderstanding of human beings. It may be that affluence can produce wellbeing, but that does not prove that wellbeing depends on affluence. Indeed, the conception of human beings upon which the sufficiency economy is based is one in which there are an infinite variety of fulfilling lives that can be lived while consuming no more than an equitable share of nature. Put more directly, the sufficiency economy is based on the premise that 'a simple life' can be 'a good life,' a truth that is obscured only to those who have not sufficiently explored their imaginations. Since consumerist conceptions of 'the good life' are causing devastating social and ecological problems, it follows that our economies should promote conceptions of the good life based on far lower resource and energy consumption, and that is the defining characteristic of the sufficiency economy. 3.2. The Macro-Economic and Lifestyle Implications of Energy Descent The necessity of highly reduced energy consumption is perhaps the critical issue (Odum and Odum, 2001). Such a reduction will arise whether it is enforced by declining oil supplies or voluntarily embraced as a response
