Potentially? I DOES leave many parent childless when their only child dies.
It was one of the first things I noted when the plane crashed. Communism sees no value in an individual. Simply another person. To the communist mind, their death can be tragic but the complete picture is overlooked. The tragedy of a devastated family doesn’t exist.
Consider this, with only one child, there will be no uncles/aunts. Then there will be no cousins. There will be no family. Communism destroys families.
