Forget the economic aspect of it, what about the emotional and mental cost something like Downs Syndrome imparts, for both parents? I can't imagine any parent hoping they will have a child that will be utterly dependent on them for their entire lives. It's not at all to say they do not love their children as they are, but nobody seeks to become a parent hoping their child will have severe developmental disabilities. While some may choose not to terminate the pregnancy, I think most parents would think twice before conceiving if they knew with reasonable certainty before the fact.
