And I agree with that. Why should someone who knowingly births a child with a high chance at disability be afforded taxpayer money to take care of that child? Obviously there would need to be some "percentage of disability" threshold established, but I don't agree with the idea that people who knowingly dig themselves into a massive hole should place the burden on everybody else to get them out.
Of course that is completely unfair to the child, so it's hard to work around that idea. The child is not at fault for the decisions of the parent, so the question is truly one that there is no good answer to.
