‘A world without people with Down syndrome.’ At what cost?

[T]the dream of a world without Down Syndrome masks an ugly reality. As difficult as the condition’s effects can make life, they hardly guarantee a life of misery and emptiness. Down patients are still capable of leading happy, rewarding lives—that is, if they’re not snuffed out in the womb first. Nobody can fully know the fruits or fulfillment of another’s life, especially one that’s barely even begun. However empathetic the intent may be, killing someone to spare him or her an uncertain future is as shortsighted as it is arrogant.
