I recently started a book on a similar subject - "The End of the World is Just the Beginning" by Peter Zeihan. It mainly discusses the coming demographic bust most places in the world will see, and how that will lead to a breakdown of the author calls "The Order" - the American-backed protection of cheap and safe transport of materials across the oceans.

He sees a bright outlook for America, which can create all the energy it needs at home, and a bad outlook for places like China, which imports almost everything.

I recommend the book, but I do think he doesn't do a great job of making a solid argument that the demographic bust must lead to "the end of the world".
