Thank you so much for your note. Now I see your comment "No, the major challenge,..., is to convert these ideas into action."
I have "The Upside of Down: Catastrophe, Creativity, and the Renewal of Civilization" but have only scanned it. The same with his "Environment, Scarcity, and Violence". I omitted a reference to them because he makes things a bit more complex than they are, in my opinion. That is why I went with Tainter. For example, I agree with Friedman that the Federal Reserve was a big mistake. I suppose he would call me a "neo-Malthusisn". I did like his stages of denial, some of his income gap comments, and the chapter of "why don't we face reality". You can see examples of the latter in these essays.
All his tectonic stresses and conditions in Tainter are present today and have been for a long time. The limited space left me with commenting, "However, the collapse is a failure of the society's organization to adapt to nature and to the changing conditions." That is, he is only describing some of the natural conditions imposed on humanity all th time.
Let me take this opportunity to address another idea I think you are tending toward. Almost all the essays have suggestions with little chance of happening. My last comment "The barons are organizing." suggest the required action is already happening. Look at the conditions that forced the barons to action. They are all present in the US today. Many today are already taking action toward a thing like the Magna Carta that I suggest is a new constitution. The TEA party (they want a smaller Federal Government) is becoming stronger. The secession movement is small but growing. Many are writing books and article s suggesting constitutional amendments (Friedman, M. R. Levin, R. E. Barnet, etc.). The path toward the kind of constitutional change is already happening. I hope the leaders of today are as smart as the leaders in 1787.
