Abortion

I think Daniel did a fantastic job at discussing the abortion issue while noting the biases he has that naturally come with the topic, and pushing them aside to dig deeper into the issue.
One point that was not raised though, is the quality of life of the child-to-be. For instance, in the very extreme example that the mother and father are crack addicts that are one the road to spending their lives in jail, the child will most likely be put through an orphanage/adoption agency/foster homes or sent to live with other family members, such as grandparents. In the first scenario, the child will grow up with many unanswered questions, most commonly why their parents didn't "want" them, or if their parents are even alive. In the second, the child has too many answers in that they know the fate of their parents and are left to deal with the repercussions left on the rest of the family.
While adoption is absolutely fantastic, there is an alarming number of children in orphanages and foster care. Furthermore, foster care is especially stressful for children because they are moving around and constantly having to get used to different living environments and friends, and often can even be separated from their own sibling(s) eventually.
These experiences are likely to cause children and adolescents to develop mental health problems, and can even lead to suicide. Doesn't this defeat the purpose of saving this life?
My point is that, if we are looking at this issue from an equality standpoint, the equality of life quality must be considered. If a child is going to be miserable because the parents know from the beginning that they will be unable to provide an adequate life for the child, maybe abortion should be an option.
