Here is a more relevant critique of your position: Notice however that the issue here is per capita income. The relevant metric for wartime capability is a nation’s total productive capacity. Total productive capacity of a nation does increase with population and we can prove this with a simple thought experiment.
Point taken. Here is the problem with this argument: labor isn’t the only input to productive capacity, and China’s population is far passed the point where labor is the bottleneck. If China can’t get enough oil, gas and other resources to fuel its industry and feed its people, it won’t matter how many workers it has.
New babies are not born with a ticket that entitles them to a percent share of world GDP or land or iron ore. In practice they get a lot of support from their parents if they are to survive, but that’s not really relevant for the purposes of this thought experiment because we can imagine them now at 18 years old and kicked out of the house with no money. Since on average these new people are still able to sell their labor on the market for more than it takes for them to survive, we can assume that they are contributing to China’s economic size.
If you’re going to use GDP as a proxy for power, well, I regret to tell you that China was by far the largest economy in the world in 1840 when they got their ass kicked by the British, and again in 1860. They lost to Japan in 1894 despite having 5 times the GDP.
No, most of those resources would remain unavailable to you. This is an important distinction. You wouldn’t even “own” any of those resources because you wouldn’t have the manpower to actually dig them out of the ground or capture them. You would not be able to get any of the sunlight by building solar panels, or extract the coil and oil from the ground. The only resource you’d instantly “own” in a trivial sense would be the stuff that you could walk to and find some way to pick up, like the land in a certain radius around wherever you were.
When you imagine this scenario, I want to make sure you’re not imagining a scenario where everybody in the world disappears, as that’s not an analogous example. The actual world is filled with secondary goods that people built, not just premined coal and oil. The default one person world in your mind’s eye should be Eliezer Yudkowsky transported to 10,000 B.C.E.
That… is what I said with “you can’t run a modern economy all by yourself”? Are you just arguing for the sake of arguing?
This seems like an arbitrary number and I don’t think you actually have any mechanical reason to believe this is the case. I would like to know what you believe are the hard limits on, for example, food production and city planning. Why wouldn’t we be able to just scale up the solutions we already have?
Correct, it is an arbitrary number. If you’re not convinced that a world with 200 billion people and our current tech level is horrible to live in, take 2 trillion instead. The whole point is to dial the number to the extreme end of things, why bicker about this detail? The reason we can’t just scale up current food production solutions, i.e. farmland, is because half the habitable land on Earth is already used for that purpose.
You just state this is “what you believe” and don’t explain why you believe it. There are plenty of obscenely rich people in Silicon Valley today who would not win a positional game on business leadership in a million years but got lucky picking a correct idea. And if your society mints 50% less entrepreneurs or engineers, you have 50% less opportunities for one of them to spend the trivial amount of resources coding and deploying a test version of Google. The faster the microchip/the microwave/the radio/etc. is developed the faster spinoff technologies can be developed and the more information the rest of the nation has on the search space for new tech.
I believe what I wrote because what you theorized has not come true in China or elsewhere. Shockingly little technological progress has happened in the last 20 years despite record levels of university graduates all around, this fact has merely been obfuscated by catch-up growth in China and other developing countries—a growth model that I predict can’t be copied any more by e.g. India.
I’m at a loss as to how this is supposed to follow. Do you think globalization causes poorer countries to increase in population and thus use up more global resources?
No, quite the opposite. Globalization reduces population by making poorer countries wealthier, which is good both directly and indirectly.
But then this goes back to the fallacy that new people come with a share of world per capita income. The Chinese aren’t using up land Americans owned before they started trading with them.
They can compete for limited resources with their labor and thereby acquire a share of world per capita income.
Point taken. Here is the problem with this argument: labor isn’t the only input to productive capacity, and China’s population is far passed the point where labor is the bottleneck. If China can’t get enough oil, gas and other resources to fuel its industry and feed its people, it won’t matter how many workers it has.
As far as I can tell, we can settle this entire debate with one concrete question: of all the consumer goods China’s/Your/My population(s) are buying, what percent of their value is due to the basic inputs like rented land and minerals, and what percent of their value is due to labor? Then apply your laffer curve and we will be able to calculate exaclty when new people “should” reduce per capita income statistics.
Correct, it is an arbitrary number. If you’re not convinced that a world with 200 billion people and our current tech level is horrible to live in, take 2 trillion instead.

Well, partly because it sounded wrong and I like to bicker, and partly because the specific numbers are important. You’re making a specific claim about 7 billion people being “too much”; I was wondering if you had any modeling behind this.
If you’re going to use GDP as a proxy for power, well, I regret to tell you that China was by far the largest economy in the world in 1840 when they got their ass kicked by the British, and again in 1860. They lost to Japan in 1894 despite having 5 times the GDP.
I used the term “productive capacity” to more closely hint that that it’s something more like “GDP per capita—subsistence income”. Obviously if you’re spending 90% of your economic and productive resources keeping your own population alive, or if your state doesn’t have the political will/infrastructure to tax that income, then that GDP can’t easily be reallocated towards wartime spending. In modern economies we have a lot more wiggleroom and so GDP itself more closely approximates “wartime production power”.
Of course it’s not the only thing. Governors can just fail to use the resources they have to protect their citizens. But spare change to buy guns, missiles, etc. is a resource.
That… is what I said with “you can’t run a modern economy all by yourself”? Are you just arguing for the sake of arguing?
I’m doing this to point out that the “laffer curve” idea is flawed. Increases in population can also increase basic resources per capita by allowing society to scale up extraction and mint engineers that make efficiency and usage gains.
They can compete for limited resources with their labor and thereby acquire a share of world per capita income.
And again I’m confused. What’s the problem here? In order to “acquire” that “share”, China has to buy those resources from the United States, with something of equivalent or better value—mainly the fruits of their labor. They are not gifted that land from the United States as a trophy for being economically globalized, they enhanced their nation’s productivity and now they are buying it with all of those secondary goods they’re making, goods that we value as much more than the land itself. This is just a misunderstanding of how markets work.

Doing multiple comments to keep track of different threads.
