I will likely get flamed for this, but to advocate living wills as a means to avoid 'needless expenses' is not in and of itself anti-humanitarian. One who signs a living will has the right to deny extraordinary medical intervention. Without such wills, the medical community can run amok.
You should not be flamed for ANYTHING. I don't approve of flaming, or of trying to get rid of posters I don't agree with. These seem to be immature practices to me.
I think the concern here is with that old slippery slope of setting a monetary value on human life and at what point granny becomes too expensive to keep alive. A lot of people would think that might be right after she's eligible for AARP if it would increase the estate, and they wouldn't hesitate to use the government to enforce their greed, if they can.
I agree with you about the need for living wills. But they are useless if we have a society that doesn't value people's rights and wishes.
