And that's the top of the hill. Once society officially deems a group of people not worth caring for, the bar always moves toward caring for fewer and fewer. Today it's "Let's let the terminally ill and elderly die". Tomorrow it's, "Let's help them die quicker because it's more merciful". Then we eliminate the severely mentally ill, for their own good of course. Then the not so severely mentally ill. Then, the disabled who require expensive accommodations. Finally, the ones deemed responsible for society's ills. Sound familiar? It's happened before.
