Same basic theme, that most of the elements of collapse are in play that point to a probable decline, or worse.
I'm more optimistic, because technology can break through to boost economic conditions (which inevitably increases disparity, which is one of the elements of collapse), or people can simply stop spending money they don't have.
... on a tangent, I'm listening to this boring sounding guy talk about population collapse. The startling fact standing out to me is his claim that no country that had experienced even a slight decline in population due to diminished birthrates has ever recovered.
The other conspicuous yet not often considered fact is the #1 best predictor of population growth rate; how many children women say they want to have. For a population to stabilize, it "simply" requires women to say they want the number of children that creates that population growth rate.
Finally, even Africa, the only place in the world with a growing population, is experiencing a declining population growth rate.
