Resources are limited. That's an unavoidable fact. If you don't like it, go complain to God. Given that resources are limited, it's also an unavoidable fact that every time we spend a few hundred thousand to give someone a few extra months of lousy quality life, that's a few hundred thousand not spent on something else -- all while millions of children in the 3rd World are dying before age 5 every year, for lack of a few cents worth of anti-diarrheal medicine, and a few dollars from some low-paid aid worker to dispense it. Why is a few extra months of some elderly Westerner lying in a bed no longer recognizing friends and family, worth so much that it warrants letting a few hundred African children die before their 5th birthdays?
