...the one that was changed a decade ago?
That would make them the first country to do so, I think. Others have tried and nothing has worked. But China will likely become rich before it gets old, so it may not matter.
Their population is declining already and they have a very long way to go before being considered "rich", so I haven't seen many projections for what you said. If you meant it, I'd be curious to know why.
He didn't say the policy can't be changed. It was. The issue, not so easily.
If there's one thing China learnt from the USSR was on how to be part of the globalisation push, and get as an advantageous of a position as they possibly could, in that the CCP has been very successful.
We will see if the shift to more authoritarianism from Xi will unwind that but China's future, with all its issues, is starting to look brighter than whatever the USA has become. Perhaps limiting the influence of the finance industry has a much better long-term prospect, it's very much one of the major flaws of the American system leading from the 1980s.
like every other civilized people, the Chinese have largely realized that the game is rigged and the only winning move is not to play. the only way to "fix" the birth rate is to reject humanity (education, urbanization, technology) and retvrn to monke (subsistence farming, arranged marriages, illiteracy, superstition), which no civilized country will ever do. even the current TFR of 1.0-1.5 in the civilized world is largely inertial, and it will continue to fall. South Korean 0.7 will seem mind-bogglingly high a hundred years from now,
and 1CP was such a predictably disastrous idea that I seriously doubt the forward-thinking you seem to believe the CCP to posses.
If you want to talk demographics, there are a lot of places that are way worse off than China. Obviously there are the usual suspects, S.Korea and Japan, but also Germany, Italy, and Spain. (Europe's largest economies, France aside... and I'm not so sure about France!) All of them have demographic situations that are far worse than China's, unless you genuinely subscribe to the notion that they can somehow be fixed via mass immigration from third-world countries.
They won't do it willingly. That just means it will happen without their input.
the ideal family has two full-time working parents, paying a mortgage and car loans, consuming as many high-margin domestic products as possible, rearing as many children (future laborers and consumers) as possible, with little to no assistance from the state. and you simply can't have that by force. if you could, you might as well drop the pretense and openly treat your population as slaves.
There are a lot of people who do subscribe to that, mainly people who are on the left side of the political spectrum. Heck, the entire Biden administration believed that.
IMO, India likely won't make this transition. It's population is still growing but it's birth rate is sinking fast (like most everywhere else).
India's demographics don't look as bad as China's, so I'm not sure why you're less optimistic about them.
