China's child tax is becoming weaker, and I learned the other day that there are talks of removing it simply because no one thinks that if it was removed they would have another population boom in the cities(although they had to revise peak population estimates from 1.3 billion to 1.6 billlion...since we are already at 1.3 billion

But to give them credit, without population controls they estimated they would have peaked at around 2.3 billion people). The life styles of the cities simply isn't conducive to having 5-6 children (Small apartments, little privacy, no economic incentive for multiplie children). The countryside can be considered another story, but even where people outright ignore the quotas of the government, they are most likely on their own without too much gov assistance in the first place.
The real "solution" needs to come through a variety of means, with these only being cherry picked as to what I can think of
*Firstly - as other posters echoed - we ALREADY in the "first world" don't have that many kids, and without our immigration our populations would be declining. Countries that have incredibly strict immigration quotas - a la Japan - are decreasing. Foxery - how do you cite a place like Tokyo? Japan already has negative population growth.
*"Modernizing" (however we should carefully define this) will decrease the population simply because the new lifestyle doesn't promote children. If you are poor, your children become economic capital such that they support you. they become the types of goods you can produce. Those with a different lifestyle have their own forms of this economic capital, and thus their incentive is about producing fewer children. This holds true especially if you are a farmer with little to no mechanization because all labor then comes from a human.
*Technology will help us. But as Hayabusa Rider pointed out , we CANNOT rely on this. To allow a fire to burn a house down, all the while saying "the firemen will come" isn't going to help if there isn't any firemen in the entire region. Technology let us leap over fears of overpopulation and mass starvation in the 1970s, but we can't necessarily rely its going to happen again. If anything, planning for current technologies that exist is what should be done. We shouldn't necessarily forecast technologies that are still in research. We can't be AMD in the late 90s computer slump who plowed forward; its better to act as intel in this type of case
*Giving aid to countries isn't necessarily going to help them NOT be hungry by filling them with more food. We assisted India in increasing ag output and guess what happened? Population boom and even MORE people are now hungry. The real solution will be to let them develop to a point that having as many children isn't the desired factor.
* we have NO right to dictate who can or can't have children. If you want to have 6 children - you have every right to have six children regardless of if you are in America or in Africa.
* Lastly - this ISN'T a short term solution by any means. The fact that the only real proven method of having people voluntarily wanting less children is to a life style that does not promote it. Other methods we could institute, such as spreading a plague, causing starvation, and engaging in war is unethical imo. We've already seen the devastating effects of them in history and there is no reason we shouldn't pursue an alternative amount...especially considering the scale it would have to be preformed on.
* Oh and second to last...no one is still really sure exactly what should be done. We should still discuss it in order to gain a better understanding and become aware, but we need to hesitate at actually controlling the population and dictating who can or can't have children.
