I will ration my own health care, not someone else's and I don't want someone else rationing mine.
One thing that many people overlook is that once we start deciding that death is the treatment of choice for serious illnesses, we have removed any incentive for drug companies or scientists/physicians in general to seek cures.
Many things that were once very expensive to treat and had a hopeless prognosis (childhood lukemia, for example) by now have almost routine treatments and a high level of success. In addition, in the course of treating for extreme conditions, cures or ameliatorive treatments are often found for more ordinary ailments, and this may even result in a decline in the cost of treating them.
In other words, by giving an automatic death sentence to anybody who has a serious expensive illness, we are cutting off the way to future treatments that may benefit us all.
But that sums up utilitarian, socialist society in a nutshell: shortsighted, hopeless, and uninventive.
If an extra six months doesn’t matter, then soon they’ll be saying that an extra six YEARS doesn’t matter.
