I remember when I was being told about the dangers of drugs, someone said, "The reason why people will push drugs on you is to legitimize their own choice."

I think that applies in this situation as well.

While there are a lot of people, there are not so many children/youth. A big problem, at least here, is that we have a growind elderly population and a smaller workforce to replace them. Understandably, fewer women are having kids.
