If your logic is that - because of a demographic reshuffling towards a higher median age slated to occur over the next two decades - China will be unable to participate in global power play and politik, despite the fact that, over the same time span, China will maintain a youthful portion of its population that would be almost double the population of the entire United States, then - just to be able to keep coherence - you'd immediately need to reassess your claim that Western countries would be better able to face these challenges or you'd have to consider the possibility that their ability to force-project would decrease at a rate higher than that of China's.JanJelleNL wrote: ↑Mon Jan 03, 2022 12:25 pm But many 21st century challenges scale up with population size. More people means more mouths to feed, more water to source. I think China will eventually figure out ways to get out of those crises, but it will take a lot of resources. Resources that cannot be spent on fighting a cold war.
Many Western countries also have insufficient pension savings and looming challenges for mitigating and adapting to climate change. But they do have more wealth to draw on for facing these challenges.
Excluding the United States, whose lead is rapidly being lost, there is no Western country with a higher percentage of the world's wealth than China. The western runner-up, Germany, has only a quarter of China's wealth, and is likely to take a non-adversarial role due to their economic and energy resource-based links with Russia and China.
China doesn't need to make the process easier or increase the migratory flow. They're not like Japan, who really ought to have allowed more immigration but didn't due to cultural reclusiveness, xenophobia and a desire to preserve the Kawaii aesthetic. China has the propaganda apparatus, educational system, governmental focus, and good stock quality (as in, people quality) necessary to continuously cultivate productive and adept members of both leadership and STEM sectors.JanJelleNL wrote: ↑Mon Jan 03, 2022 12:25 pm Differences in living standards may not be as extreme as they used to be, so migration flows can become gradually less one-sided. But we don't need everyone to come over, just enough to keep the engine going. I think for China this is more difficult, it's just not an easy country to migrate to and put your roots down (or is this a Western perspective, is it easier for non-Westerners to fit in there?). Japan struggles with this too, they could really benefit from some more (skilled) immigration but either don't want to or don't know how.
Let's get a bit more abstract:
If a system requires exhaustible external energy in order to perpetuate itself, then it is unsustainable by definition. So, if I may use your analogy, if the US is a person transported in a Car OF FREEDOMTM powered by an engine that must be constantly fueled by gasoline sourced from outside the vehicle's own range and if that source could run out, then that vehicle is de-facto inferior to something like a tricycle because the tricycle is propelled by human work undergone by a body whose fuel could be sourced well within the range of the individual's athletic ability.
