Just wait until a luxury cruise liner hits it and and gets shit everywhere then they might clean it up.

Like Titanic except they will wish that the ship went down when they are covered in literal months old rancid fat.

Short version - there’s too many elderly people in China and not enough working age so the economy is suffering. So they changed it to max of 3 but people aren’t interested in having more than one. This will take a long time to recover from. As their society has seen a drastic disparity in age and sex, the importance of women to societal growth means that women have more bargining power to push for woman’s rights. While India continues to breed like rabbits.

As a side thought, I wonder if this will push China to take drastic measures rather than see their country wither away.
