On the future of the U.S., or of Western civilization in general, I tend to be quite pessimistic. I would say that today I see most of the symptoms of societies on the brink of collapse, not just in the U.S., but in the tightly interconnected societies of Western civilization - now essentially world civilization.

The key strengths of civilizations are also their central weaknesses. You can see that from the fact that the golden ages of civilizations are very often right before the collapse. The Renaissance in Italy was very much like the Classic Maya. The apogee was the collapse. The Golden Age of Greece was the same thing. We see this pattern repeated continuously, and it is one that should make us nervous. I just heard Bill Gates say that we are living in the greatest time in history. Now you can understand why Bill Gates would think that, but even if he is right, that is an ominous thing to say.

With apologies to the green movement, "sustainability" is a myth. History and archaeology show that societies are always moving to the edge of crisis, "falling forward" through growth, but then responding often successfully to the problems created. What we can hope for is that with a somewhat more controlled level of growth, and with longer-term preparations for change, we can keep responding to the inevitable smaller crises, as they arise, and continue to postpone until later and later the, perhaps ultimately inevitable, end of our civilization.

Leaders may recognize that they are not addressing the real problems, but they rationalize their actions with the argument that they must first politically survive in order to later address the hard problems and sacrifices. Of course, they usually don't ever actually get around to addressing the fundamental problems later, either because they don't make it through the initial crisis or because, even later, they are not willing to risk sacrificing their own position or "career" with needed measures that usually require tough sacrifices by the population.

When there is pressure for leaders to respond to problems or crises, they often simply intensify their efforts in their particular defined sphere of activity - even if that's not relevant to the real problem. To do otherwise requires taking on entrenched practices and asserting power in areas where it often will not be well received. And leaders tend to see major crises more as threats to their own position rather than as systemic challenges for the societies that they govern or the institutions that they manage.

No society can sustain unlimited growth - none ever has. History demonstrates that expectations of infinite growth lead to collapse. Unfortunately, millennia of evidence also indicates that needed attempts to stabilize such societies run counter to the expectations of the populace and of interest groups. For that reason, such attempts at stabilization frequently fail.
