 In a finite world, longer-term models need to take into account the fact that resources deplete and the population keeps rising.
Any modeler who tries to take into account the fact that resources deplete and the overall population keeps rising will quickly come to the conclusion that, at some point, every economy will have to collapse. This has been known for a very long time. Back in 1957, Admiral Hyman Rickover of the US Navy said,
Surplus energy provides the material foundation for civilized living – a comfortable and tasteful home instead of a bare shelter; attractive clothing instead of mere covering to keep warm; appetizing food instead of anything that suffices to appease hunger. . .
For it is an unpleasant fact that according to our best estimates, total fossil fuel reserves recoverable at not over twice today’s unit cost, are likely to run out at some time between the years 2000 and 2050, if present standards of living and population growth rates are taken into account.
Now, in 2021, as it looks as if this problem is starting to hit us. But no one (since Jimmy Carter, who was not re-elected) has dared tell the general public. Instead, accrual accounting with more and more debt is used in financial statements, including GDP statements. Actuaries put together Social Security funding estimates as if the resources to provide the promised benefits will really be there. Climate change models are prepared as if business as usual can go on for the next hundred years. Everything published by the mainstream media is based on the underlying assumption that we will have no problems other than climate change for the next 100 years.
 About all that can be done now is to start cutting back on the less necessary parts of the economy.
President Biden’s abrupt pullout from Afghanistan reflects a reality that increasingly has to take place in the world. The US needs to start pulling back because there are too many people and not enough inexpensive to extract resources to fulfill all of the commitments that the US has made. As mentioned earlier, there are a number of obstacles to success in Afghanistan. Thus, it is a good place to start.
With the need to pull back, there is a much higher level of conflict, both within and between countries. The big issue becomes who, or what, is going to be “voted off the island” next. Is it the elderly or the poor; the military or the oversized US medical establishment; university education for a large share of students or classroom teaching for young children?
We don’t seem to have a good way out of our current predicament. This seems to be what is behind all of the recent internet censorship. Renewables and nuclear require fossil fuel energy for their production and maintenance. The powers that be don’t want anyone to know that nearly all of the “happily ever after using renewables” stories we hear are based on wishful thinking.
