When it comes to the welfare of these people, the only thing relevant to me is a solution. At least ancient societies, cruel as they were sometimes, had a solution. Greek provinces killed "defective" children at birth. Nomadic tribes have been known to take the elderly off their shoulders and left them for dead as the rest of the tribe moved on. We're a resource rich nation, and unlike nomads constantly on the lookout for their daily bread, we don't have to do that. We have the infrastructure and medical knowledge to provide some of the disabled a decent quality of life. There are many solutions to treat people, like never before. We can also go the other route and put a bullet in their heads. At least that's a "solution", and we can move on and brand ourselves as the cold, darwinian bastards that we are. But to have some arbritray limit on what "government" can do is a cop out. It's doing the same thing as leaving people for dead, but not wanting to admit it. It's a passive solution at best. Instead of putting a bullet in their heads, you just let them fester in the streets. Of course, some of those will be treated by private organizations and churches, but it hasn't exactly worked out all that well.
