Suppose the parents have taken care of the disabled child since birth, but now they are old, disabled, or dead? Suppose they have not been able to create a trust big enough to support the child for the rest of his life, perhaps forty years more?
And please remember, having a disabled child is likely to limit one’s ability to earn money in the first place, and entail greater expenses for his care, making it harder to come up with this trust.
And some disabled people’s expenses will exceed any ability of their family (how extended, btw?) to provide for them.
Well, there is charity, and perhaps many of us would give more to charity if we were not taxed so much.
There is also considerable abuse of SS disabilit payments, another story.
A country that won’t help little old ladies or blind retarded folks is not a country I want to live in.
