9.56 million, basically an entire nation. To feed, to educate and to employ. Every single year. And worse if the number for some reason increase.
Firstly, that number is heavily disputed on Zhihu, but let's take that number on face value.
Second, that number is enough only to sustain half of China's current population
Third, US and Europe both had around 3.5 million births each, Add in Japan, South Korea, Australia, etc and you are almost reaching that amount of births.
Fourth, these countries in the West are able to attact the best talents from around the world, as well as quite a big number of immigrants.
Fifth, the births are still on the decreasing trend. They halved in last 10 years, and might half again unless drastic action is taken.
Sixth, now what will you even think about India's 20 million + births. The births are 2.5 times that of China, and India's per capita GDP currently is 1/5th of China. Even India makes zero progress on per capita performance, India's GDP and other metrics will all be within 1/2 of China already. And there's quite a lot of reason to believe that India might bring its per capita performance from 1/5 to 1/2 that of China.
The thing is that you guys are taking the best case scenarios for China for granted. I am saying that leave alone the worse case scenario, even a little bit of underperformance or some assumptions breaking would bring China in severe distress.
