CityDweller, I found this video helpful. You may not agree with the politics of it (which mostly come in at the end), but I thought it did a good job of explaining how money is created and why that requires unending expansion. (I had read about how this work, but it didn’t make complete sense until I saw the video.)
I got the link from one of the housing blogs, but I can’t remember which one (perhaps it was even from my first love, Piddington’s). Unfortunately, I don’t have time to research it this morning so as to give credit where credit is due.
