By this point in the song, modern society must feel pretty self-righteous because we haven't made the same colossal mistakes that these biblical cities have. However, the next couple of verses are dedicated to exposing the deep flaws in our society - letting us know that we aren't as perfect as we'd like to think. The narrator predicts that our society "will be sleeping" when Jesus comes back for the Rapture. They believe we will be so caught up in our superficial society that most of us will be devastated and left behind when Jesus comes back to save his believers from this tainted world.
The line that relates to the One Child, One Family policy in China is when the narrator is referring to modern day society and says "while we're sung to sleep by philosophies of 'save the trees, and kill the children.' Will we be sleeping?" This line hit me hard the first time I heard it because it's disgusting, but it's so true that we care more about the environment than valuable lives that we forfeit for our own convenience. However, when I was listening to some statistic today in society class, the meaning of the lyrics escalated.
A couple of years ago, China's government instituted a rule where families could only have one child to bring down the population. Because of this, abortion rates skyrocketed. Some women were even tortured and forced to abort their children. Also, boys are more productive than girls, so if a couple bears a female child, it is not uncommon for them to kill the baby. In some cases, the babies' sculls are even crushed after birth as a "humane" way of killing them. So, what are the perceived benefits of these horrific means of population reduction? Well, they hope the environment will be less stressed with less people and they believe that if there aren't as many children, then each individual child will get more attention in school; thus, China can raise smarter kids.
