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.

These strengths, and our civilization in general, have reached an apogee with the end of the apocalyptic threats of the Cold War and the end - or at least waning - of less successful, and ultimately less "just," political and economic systems. At the turn of the 21st century we appear to be entering our greatest century, a golden age. The challenge that we face is similar to that of the Classic Maya civilization: we have set in motion a "runaway train" of success.

"Hypercoherence" is one of the most dangerous threats to the long-term survival of our civilization. Hypercoherence is the close efficient linkage of all parts of the world economic, communication and transport systems. It has been crucial in the spread of great innovations, the rise of world wealth, and even the dissemination of democratic concepts and ethical values and the defeat of oppressive regimes.

One of our great strength, world capitalism, is the most successful economic system possible, but has also become one of shorter and shorter cycles of evaluation. CEOs, companies, stocks, profits and debits change at an ever more accelerated pace in response to the demands of stockholders and the market. We have already experienced some consequences of the shortening cycle of decision making in business, but those are minor in relation to the grand systemic collapse that always eventually results from such accelerating and shortening periods for leadership goals.

The possible signs of a coming collapse are the same as the greatest strengths of Western civilization: democracy, capitalism, the generally peaceful linking of world economic systems, our amazing success in harnessing the powers of nature to the betterment of the human condition in health, subsistence, longevity. These are the hallmarks of our society - its most successful elements.

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.
