Postmodern explanations of consumer behaviour stress social and psychological factors to the neglect of explanations based on structural issues such as the working life conditions which favour a work-and-spend lifestyle, the conditions of urban living or the effects of pervasive marketing. This paper argues that consumers may not be so keen and willing but are rather locked-in by circumstances. Some of these circumstances are deliberately created by other interests, and a policy to limit consumption must look for adequate means over a large and varied field. In the end shorter working hours may be an important key to a more sustainable future.
