I have been looking into this question for a number of months now. For many the gut reaction is consumption is bad and we should reduce our output of products that saturate the market place. Another viewpoint though would be to look again from a clean slate, starting at the beginning to see if we can consume, but in different ways. An interesting project that my colleague Andrew found was WANT. The article originally posted on Core 77 is an interesting one in the sense of consumption and the questioning of consumption.
