China is looking to solve it's short term problem by exacerbating it's, and the world's, long term problem. By increasing the population of this generation to take care of the older generation they will have to increase the size of subsequent generations to take care of the increased size of this generation. And so on ad infinitum. Eventually the constant increase in population is unsustainable. You can't have infinite growth on a finite planet. We can argue about the carrying capacity of the planet but that it will eventually be reached is undeniable. We are at nearly 8 billion. Is that the carrying capacity? Is it 10 billion or 12 billion?

Even if we can produce sufficient food there are questions of quality of life when we are that crowded. We are close to creating a planet with people and the animals that people domesticated to eat are the only animals on the planet. Excepting perhaps for rodents. Is that the planet we want to create? Then there are questions of lower crop yield with global warming and depleted fishing stocks with warming and acidification of oceans

Population growth is slowing down. I think that's a good thing. Eventually we are going to have to figure out how to take care of the elderly while stabilizing the population. I think we should start doing it now. Not incentivizing increased population growth.
