I'm very curious how China will adapt over the next couple of decades. Their population has started contracting, and it's clear the government has seen the fertility rate as a problem for some time. There's no obvious way for them to keep economic growth going without either finding a solution to something nobody else has managed to solve (getting the fertility rate back up), or opening up for more immigration. Either will take significant changes.
> finding a solution to something nobody else has managed to solve
In the 21st century, that is definitely something I'd bet on China for being able to do. Across all sorts of problems.
The solution is going to be paying people. No, more than that. No, keep going. Higher. Market-clearing price.
Fertility really 20/30+ year away problem.
PRC growth now based on educated population, which exploded, not total population. Reality is every tertiary median to upper middle class wage is more productive than 10 undereducated peasants... the ones first to age out. There's like 200-400m+ bluntly useless mouths dragging down productivity/per capital metrics, the only saving grace they did NOT get rich before old, i.e. poor old so it's cheap(ish) in terms of resources (but not labour) to support them. Put it this way, PRC is generating OECD combined in tertiary, disproportionately STEM, they have backlog of 200m births from last 20+ years that still haven't got their masters/phds... at 60% and increasing tertiary we're going 100m+ high end talent, aka the greatest high end human dividend in recorded history who will be in workforce for until 2060s, i.e. so far out its hard to project based on present realities, only they have no shortage of advanced economy growth potential. Like if you throw all projected US newborns + immigration into STEM... PRC would still come out FAR ahead. There is no contest, unless AGI displaces everyone.
TFR real issue probably 30 year out. There will be some rebound, current crashing TFR because so many entering tertiary last few years = delay family formation. Women going to turn 35-40 and realize they want kids... and have them, especially considering 1:4 dependency ratio also = 4:1 wealth transfer + property going other way when previous generation (with high savings rate) dies. But won't get to replacement level. Then it's matter of what bad levers PRC willing to pull - pro natal fertility policies does not incentivize 2.1 TFR... and no one has tried punitive policies, i.e. limit wealth/property transfers to families with 2 kids... all sorts of inducements liberal societies haven't... or politically can't try. Or immigration, test tube babies, who knows. But IMO they try punitive policies first. That's really the only thing that no one has tried, and we know from wealthy Muslim countries with oil money, religious incentive, domestic help... aka every support imaginable, TFR is below 2 or trending towards it.
