EDITED:There's not much there I can disagree with (I located and read Part I, too). But neither is there much there we didn't see coming, either. Those conclusions were already being discussed and taught in academia half a century ago. America's growth was simply unsustainable. but that was not a popular position in mainstream society back then. In fact, it was considered Socialist, Luddite, downright subversive.

The fundamental unsustainability of endlessly growing prosperity was the alternative vision of America I was taught in college, and which I accepted. By the time I graduated I was convinced we were all on borrowed time and based my own long term planning on it. I'm glad I did, things worked out pretty much the way they (and I) expected, and I was well prepared for what eventually came. As I've said here before, besides the science and math, I got a terrific general education on the GI Bill at my State University.

At the risk of oversimplifying, the hippies were right. Those who took conventional American society and culture with a grain of salt in the 60s and 70s and made other plans, were not disappointed.
And today, they're not doing too bad. They may not be rich, but they're laying back, lighting up, and laughing their ass off.
