I think that Jack Ma his trying his best to reduce the Chinese population. Today Chinese population is already almost shrinking, and policies like that will make sure that having a child will be left out of the equation.

What is strange is that the communist party realized that this will be a big problem in the future, but don't link that to company policies like that...
