Is a parent's right to their own children based on something more than just the fact they are a good force in their children's lives? I read about a court case in which a custody dispute was decided on the basis of "what was best for the child". Now of course the children's interests should be one consideration, but aren't there others as well?
Suppose a baby is born to two very poor parents. A rich couple demands their baby saying "We can give your baby a better future. With us, the baby will get a better education, eat better food, live in a better neighborhood." Shouldn't the poor parent's still have a right to keep their child, even if this situation is not "what's best for the child".
