== The "selfishness" issue == 

 This section of the article starts off on the wrong foot - it seem obvious to me that it is far more selfish to have children than not. The parents cannot guarantee that the child will be happy, there are already too many people on earth, the child will use up rsources including benefits and free educvcation that the childfree have to pay for. People seem to consider having children like owning a  pet or toy. The most unselfish choice is not to have children. If the childfree are being selfish, then who are they being selfish to? If this section is written from the point of view of Catholicism, which I think believes everyone should have as many children as possible - except Nuns or priests - then it should say so.
