They're going to die regardless. Is it better to die younger from lack of health care than die older with dementia and bed sores? I've only witnessed the latter. Doesn't seem like something I'd like to go through.
I think that's a very defeatist/nihilistic point of view. Since we're all going to die eventually anyway, we should aim to improve our standards as much as possible so we or our kids get to enjoy a better old age than what old people get right now. Our ancestors have gone through much worse to build the better world we enjoy today.
