Chuck Kollars` Personal Home Ruminations


There are things I just can't figure out even though I've mulled them over a lot. Some of these are described below.

You may also be interested in some of my thoughts on either foreign policy or domestic policy, on wider common sense issues, or on further improving our government.

How Do "Modern" Economies Really Work?

Conventional wisdom says the "Industrial Revolution" allowed humankind to excape the usual constraints on animal species. Afterward, humankind could support a much larger population, with almost all individuals escaping accidental death and living to natural old age.

But actions built on this assumption have mostly failed. The World Bank and the International Monetary Fund have made strenuous efforts ever since WWII to help countries "shift gears" to join the western economies and start enjoying their prosperity. But a sober evaluation tells us such efforts have almost completely failed. Egypt has been trying for almost a century to join the "modern world", but still hasn't made it. In most countries, economic modernization has spread only to the "westernized elite" in the major urban areas.

And even in the western countries, it isn't so clear that "modernization" is really a great benefit ...or even works all that well. Most western countries have such low birth rates they can't replace their own population, and are dependent on in-migration for growth. (Some cities especially concentrate this problem. San Francisco is one of the clearest examplars of a city mostly for young adults; it gave us the term "DINK" [Double Incomes No Kids] a generation ago. The city's demographic structure has so few children and older people it couldn't possibly be self-sustaining.) Or think about what a high proportion of people around you moan loudly about their "work" and complain of too much stress. Or consider skyrocketing rates of alcoholism and mental illness.

The growth of economies of "western" countries is typically used as proof that modernization really does work. But growth of those economies before WWII may have been due mostly to expansion into the third world (i.e. colonialism) rather than integral factors. Although judged by GNP, the UK economy has grown fairly consistently since WWII, the experience of individuals in the UK has gyrated wildly; initially the UK's goal of joining the European Economic Community was seriously questioned because its economic situation seemed so dire. The most dynamic European economies seem to include a large portion of "cheating"; circumventing UN restrictions on nuclear or weapons technology seems to be a specialty of Germany; France's economy seems to rely significantly on selling weapons systems to third world countries, and there were serious questions about France's possible collusion with Saddam Hussein. Even the USA's economic preeminence may owe more to its heavy natural resource endowment and its very low population density than anything else.

Maybe rather than trying to figure out what's gone wrong in each case of stalled development, it's time to go back to square one and question the basic assumption. How do "modern economies" really work? Would they work without consuming fossil fuels? Would they still work if they encompassed the whole world, or do they only so long as lots of folks remain outside? Would they work without very significant levels of inequality?

(Often earlier economies were structured around harvesting the sun's energy biologically, and could be fully described by nothing more than the phrase "solar farming". What's the similarly simple description of how a modern, industrial economy really works?)


How many people can exist on the earth? In environmentalists lingo, what is the "carrying capacity" of our world for homo sapiens?

The human population has grown and grown and grown through time from less than 10 thousand to around 7 billion. Ecologists seem to agree that when considering environmental degradation, human overpopulation is the number one problem. Population is the elephant in the room many pretend isn't there. Efforts at rational control are likely to be unsuccessful, so humans are likely to face the same "boom and bust" population cycles that many animals face.

Various calculations and estimates of carrying capacity differ a whole lot:

Carrying capacity for humans obviously depends on what culture we're talking about. When Europeans first came to the Americas the indigenous population thought of the land as full, whereas the new people thought of that same land as empty. Some future cultural shift may dramatically raise the carrying capacity again. But should we count on it? Should we plan based on the densest culture we know of even while much of the world doesn't share that culture? Are calculations based on the Davos culture valid for the entire world including all the third world countries?

Land Use

Feeding everyone in the world is a significant problem. So I'd expect good farmland would be at a premium.

But in fact more and more flattish smooth fertile land in the U.S. is being taken over by housing. I've seen "development" displacing groves of orange trees in California and New Mexico. What I remember from childhood as a large productive valley a little south east of Sea-Tac airport between Seattle and Tacoma in Washington is now all houses with garages and yards and streets. Many localities give special tax breaks to land for agricultural use.

Why is land in this country more valuable for housing than for food? Are the economic valuations we place on things here in the U.S. just plain out of whack? Or do our values inside the U.S. diverge from worldwide values that obtain elsewhere (i.e. the U.S. is a subset)? Or is there some other explanation?

Is energy our universal/key resource?

Reducing all questions of what our population and land use should be to a common denominator of renewability (or efficiency) of energy flows seems to provide many more unambiguous answers than any other approach. On the other hand, expressing everything in terms of energy feels disturbingly similar to true believers coalescing around a religion.

A good source of a great deal of mostly numeric information with minimal spin toward any particular ideology of what energy use should be is provided by the book Energy in Nature and Society by Vaclav Smil.


The human population is more concentrated into cities than ever before in history. One place this trend toward urbanization is evident is in former colonies, which tend to have one large city per country.

All these people eat a lot, and the food has to be paid for some how. So I'd expect the people that live in a city to be quite economically "productive."

But for many of these people the simple daily logistics of shelter and transportation are so difficult they take up most of the time, leaving little or nothing for "economic productivity."

Obviously many individuals judge in the small they are better off economically living in a city than in a rural area. But what about judging cities in the large as part of an economic system? Are they economically productive enough overall to justify the fact that they exist? Does the sum of individual judgments always comprise a good system judgment?

Is Efficiency⇔Resilience A Simple Tradeoff?

Although it seems prima facie reasonable to conclude there's a tradeoff between efficiency and resilience, I'm not aware of any mathematical "proof" of any such postulated relationship. Is such a relationship circumscribed to special circumstances, or is it really a general rule of some sort ...or is it just a mirage?

It's easy enough to come up with anecdotal examples. One example: in the quest for more efficient use of their airplanes, airlines keep most of their airplanes in flight most of the time these days. There are no longer any "extra" airplanes waiting on the ground for many hours. So when some sort of disruption (such as a snowstorm closing an airport) occurs, it now takes a couple days to get air traffic "back to normal". There are no longer any "extra" airplanes to handle the burst of of make-up traffic after a disruption (in different words to "take up the slack"). Another example: Sixty-five million years ago dinosaurs ruled the earth, while mammals were just small generalists, scavenging a life in the interstices. But when a drastic disruption took place, the "efficient" species died out, while the less notable but more "resilient" species began to flourish.

But is there really such a simple linear tradeoff between efficiency and resilience? And is there actually some mathematical reasoning that implies it will always be that way, rather than just being that way in special cases? Or to say it a different way, is the efficiency⇔resilience tradeoff a "theorem" of some academic field?

The question would seem to have belonged to the "General Systems Theory" field in the past. Nowadays it would seem to be part of the problem of finding generic rules behind all systems of CASes (Complex Adaptive Agents).

Historical Change

Some see each succeeding wave of civilization as having a higher carrying capacity. In other words when two different ways of organizing humans compete, the way that supports a higher human population will usually win.

But what's next? Charles A. Kupchan in his book The End of the American Era presents the following table of historical eras. The big question is what goes in the blanks?

Era→ Nomadic
(before 8000BC)
Early Agriculture
(8000BC - 3000BC)
(3000BC - 1700AD)
(1700 - 2000)
(2000 - ????)
Mode of Production→ Hunting, Gathering Hunting, Horticulture Cultivation Industrial Capitalism Digital Capitalism
Dominant Institution of Governance→ Band Tribe, Chiefdom Kingdom,
Coercive State
Democratic Republic
Dominant Institution of Communal Identity→ Animism Nature Worship Organized Religion Nationalism

Does Demographic Expansion Imply Cultural Dominance?

Is it really true that when two different ways of organizing humans compete, the way that supports a higher human population wins?

Niall Ferguson's book on the British Empire says the single biggest factor in the British empire was the fecundity of the British population. Several countries in Europe are worried that demographic reduction means economic decline. France is worried that it will simply cease to exist in its current form because it will be overrun by the children of guest workers and political refugees within a couple more generations.

At the same time environmentalists wring their hands about overpopulation and make it clear human population is their number one problem. China wound up with a one child policy (partly in abeyance now and never completely enforced in rural areas) for decades, even though Mao initially rejected the idea vehemently.

The book Guns, Germs, and Steel by Jared Diamond suggests that whenever two cultures come into conflict the one with the higher population density wins. Similar ideas are expressed in the book Conquests and Cultures by Thomas Sowell. But how can it be true both that

  1. population growth is required for economic and political growth and innovation, and
  2. further population growth is bad and the entire earth environment is being stretched?

World Government?

For generations many in the west have had an automatic negative response to the idea of world government, but over time the reasons have been forgotten. Maybe there didn't seem to be any real need. Maybe the idea seemed over-zealous. Maybe it smacked of extending bureaucracy just for the sake of extending it. In any case the prospect probably sounded like a naked power grab.

A negative reaction to the idea of world government is also common in the developing world. But their reason is completely different; two separate lines of argument have come to the same conclusion, and it's too easy to confuse them. Many understand world government to mean hegemony of western financial institutions over the entire world, and are understandably displeased by the idea.

But the world has changed an awful lot in the past few generations, and there are now powerful reasons to reconsider some sort of world government. Communication easily goes much farther much faster. Imagine describing to your great-grandparents the idea of picking up the phone and dialing 011 (followed by more digits) and hearing someone speak a different language. Environmental actions can have ripple effects half a world away. Towing giant icebergs south to supply fresh water might change the climate of Siberia. Huge uncontrolled forest fires in one country have created so much smoke they darkened the sky in other countries. Industrialization in the northern hemisphere may have caused the breakup of huge swaths of sea ice in Antarctica. Economic effects can stretch over the whole world. When the president of Maylaysia blamed the financial woes of the Asian contagion in his country on currency traders in other countries, many said his reasoning was incorrect but almost nobody said that economic actions couldn't have effects that fast that far away. Agricultural policies in Europe have measurable impact on life in Africa.

How will we decide how many people should live on the earth? How will we decide how they should be distributed? How will we enforce those decisions? National boundaries don't seem very relevant to the problem of world over-population.

Perhaps the biggest problem surrounding the idea of world government is the huge potential for corruption. So much power concentrated in one spot can't help but be greatly abused.

A second problem surrounding the idea of world government is that it might select the wrong people. The people who would thrive in an easily imaginable kind of world government would be expert bureaucratic infighters and fundraisers. But are those the people we want for world leaders?

So what are our options for making world wide decisions? Something like the UN (United Nations)? A greatly expanded NGO (Non Governmental Organization)? A parliament like in the EU (European Union) but larger? Something grown out of the WTO (World Trade Organization)? Or something else?
