There should be no enforcement at all on childbirth. China is the only country to have ever enforced such an extreme and drastic policy and will now be facing demographic collapse in ten years because of it.
Why do you think it’s normal for a govt to even enforce such draconian measures? No other country does these things. Not even North Korea.
Just becos things don't happened doesn't mean u need to take things for granted.
Just like little covid death in China, does it mean covid is really just a flu or due to China zero covid strategy that helps reduce death?
Same as China one child policy. Look at India over populated population. Do u know India unemployment rate is very high compare to China. They have slum everywhere. The lower birth rate during those period helps China to avoid lot of social unrest and overpressure on government responsible to take care of such huge population.
Policy is ever changing according to situation. Just becos China lifted one child policy doesn't means the past action is wrong. You don't take things for granted just becos bad things or unrest due to overpopulation never happened...
