Ironically the more kids you have the more competition you will have in for jobs, housing, food, resources; exactly why people are reluctant to have more kids in the first place. In about 30 years, global warming will make resource competition even more intense.Housing costs in China are insane and they will remain insane as long as the state doesn't completely nationalise the entire sector and subsidises cheap housing to young couples. That's a major reason why people don't have kids, it costs a fortune to buy a place. It's time for the CCP to show that they are a communist party in more than name.
Frankly, they sat on their asses as the gigantic failure of the 1 child policy was allowed to fester *and* the housing market spun out of control, many years ago.
Instead of focusing on having more kids, 2 trillion yuan extra a year should spent on education, improving individual productivity, automation, etc..
