Ego-identification with things creates attachment to things, which in turn creates our consumer society and economic structures where the only measure of progress is always more. The unchecked striving for more, for endless growth, is a dysfunction and a disease. It is the same dysfunction the cancerous cell manifests, whose only goal is to multiply itself, unaware that it is bringing about its own destruction by destroying the organism of which it is a part. Some economists are so attached to the notion of growth that they can't let go of that word, so they refer to recession as a time of "negative growth".
