Some of the arguments towards having kids are the lamest i have ever seen. People deciding not having children are actually doing many people a favor, because children require a lot of attention and care in order to grow up as mature man/women. several problems in this world,also, are because many parents actually never sat down and thought what means to have kids and all the responsabilities that they carry along.
In many countries, there is no such thing as pedogogy, and there is many people (note i'm not saying everyobody :)) who has kids by tons just to hope they are gonna help them with work or simply because of the tradition. So seriously, we need more people who is conscious of their decisions. having kids is more just than getting money to raise them. and getting pregnant doesn't mean you are prepared to be a good parent.
someone i know is a musician and she raised a boy from a very early age. she used to play her songs on the piano and sing to him to make him sleep. now her biological father wants him to be into sports like him, but as you can probably imagine, the boy wants to be a musician.
