The answer is simple: we have been promoting getting a selfish career, for both men and women, over getting married and starting a family. We are have less children because we have been training our children to view individual self-fulfillment as more important. In particular, we have been training girls to hate their feminine nature and seek independence outside of the home. Then we act surprised when our children grow up and act that way that we trained them.
