Machine Metaphors

I really like the machine metaphor. Here is a quote out of Derrick Jensen's What We Leave Behind that occasionally pops into my head.

"We live in a machine age. To maintain prosperity we must keep the machines working, for when machines are functioning men can labor and earn wages. The good citizen does not repair the old; he buys anew. The shoes that crack are to be thrown away. Don't patch them. When the car gets crotchety, haul it to the town's dump. Give to the ashman's oblivion the leaky pot, the broken umbrella, the clock that doesn't tick. To maintain prosperity we must keep the machines going."--Richardson Wright
