Of course there are also loyal and loving children who are more than willing to take care of their aging parents, but 40- or 50-year-olds cannot just think about raising kids as a way to support themselves in old age because they are about to come face to face with a phenomenon very difficult to reverse-the younger population will never again outnumber the older.
自然也有孝順的孩子，願意奉養老年父母，但四、五十歲的中年人，卻不能只想著養兒防老，因為他們即將面對一個很難逆轉的現象──兒童人口再也不可能多過老年人口。
