I agree with the basic premise that a severely disabled person is nothing more than a drain on society. The individual will always have to be cared for and is always costing money without every doing something for society in return (because they can't). So it's a basic fact, no matter which way you twist the issue.

However stating that because they are a drain on society we might as well harvest their organs is a little much. From a purely sterile and logistical point of view it might make sense. But from a humane and ethical one it makes no sense at all. Disabled or not, it's still a human being who has rights. Among which are the right to live and the right to medical care. Not to mention that not all mentally disabled people were mentally disabled from birth. One might become disabled after an accident or something.

The argument that should be made here is this: you shouldn't be able to have the child if early tests show that the child will be mentally disabled to such a degree that they need care for the rest of their life. One could argue that is for the parents to decide, but most often the parents are the least fit to make a decision like that due to emotional attachment (especially the mother). They would happily have the child, collect health benefits for taking care of it and spend society's money on something that is not benefiting anything for anyone ever.
