Succinct - Rotten Circuits
Well, it's not like you really need a primer any more...
I try and read all of the links you post - they're invariably interesting or educational.
The crash course it great, once you get past the first few episodes explaining the maths behind the economics, and if you can tolerate Martenson's repeated insistence that "The Next 10 Years Will Be Radically Different From The Last 10 Years!" He ties together the socio-geographical, economic, and resource and environmental factors to show why there's really no use in sticking our heads in the sand - in fact, at a lot of points, watching it made me feel like there was no use having our eyes open either! There are still two episodes to come, in which he summarises and lays out his views and suggestions.
