At the start of the oil glut, a climactic set of economic relations took shape led by Prime Minister Margaret Thatcher (and joined eagerly by Preside… - James Howard Kunstler

In any case, it is human nature to consider a place “home” if you were born there, […] have family there, or have spent some portion of your life there, and people are naturally reluctant to leave home. I daresay that many Americans now living in the Southwest will not be disposed to understand what is really happening—that the carrying capacity of their home region has been suddenly and drastically reduced—and they will hunker down hoping for a return to better times.
The vested owners of all those sun-drenched tract houses may stick around for a while and fight over the region, perhaps thinking that they are reenacting the great historical dramas of the nineteenth century—such is the long-term effect of canned entertainment on the collective imagination. The violence and loss of resources will surely send some American citizens fleeing. After a while, it will be obvious to even the staunch defenders that places like Los Angeles, Las Vegas, Phoenix, Tucson, and Albuquerque will never again support the populations that were possible during the height of the cheap-oil blowoff in the late twentieth century. They will then pack up and move elsewhere, sacrificing their houses and ties to a disintegrating community. These new refugees may move into careers that they never could have conceived of twenty years earlier, when they were young college graduates: farmer, farm laborer. Wherever they go, they are going to discover a nation preoccupied with food production above all other activities.

Everything characteristic about the condition we call modern life has been a direct result of our access to abundant supplies of cheap fossil fuels. Fossil fuels have permitted us to fly, to go where we want to go rapidly and move things easily from place to place. Fossil fuels rescued us from the despotic darkness of the night. They have made the pharaonic scale of building commonplace everywhere. They have allowed a fractionally tiny percentage of our swollen populations to produce massive amounts of food. They have allowed us to develop industries of surpassing ingenuity and to push the limits of what it even means to be human to the strange frontier where man imagines himself into a kind of machine immortality.
All of the marvels and miracles of the twentieth century were enabled by our access to abundant supplies of cheap fossil fuels. Even the applied technology of atomic fission, which came along in the mid-[20th-]century, would have been impossible without fossil fuels and may be impossible to continue very long into the future without them.
The age of fossil fuels is about to end. There is no replacement for them at hand. These facts are poorly understood by the global population preoccupied with the thrum of daily life, but tragically, too, by the educated classes in the United States, who continue to be by far the greatest squanderers of fossil fuels. It is extremely important that we make an effort to understand what is about to happen to us because it will have earth-shaking repercussions for the way we live, the way the world is ordered, and whether the very precious cargo of human culture can move safely forward into the future.

The attrition of global populations by disease[s] may be unavoidable. Some... may regard it as the inevitable revenge of nature against the hubris of a human species arrogantly exceeding the carrying capacity of its habitat. Some may regard it as a moral victory against wickedness. Some may view it in the therapeutic mode as a positive development for the health of the planet. Many self-conscious "humanists" have militated for the goal of reducing population growth—though most of them would have... preferred widespread birth control [using contraceptive methods like the birth pill and condoms, ironically made from cheap oil] to a die-off. But that kind of thinking might have been just another product of the narcotic comfort of cheap oil, as merely stabilizing the earth’s population at current levels (or even 1968 levels) would arguably still have left humanity beyond the earth’s carrying capacity. Apart from these issues of attitude and ethics, however, a major decline in world population, or change in demographic profiles, is apt to have profound and strange repercussions on everyday life.
