Longevity

Okay, thanks for the answer but I think it's only moot points ;

Yes, not everyone gets a cancer treatment when they need it, but that doesn't mean we should not pursue better cancer treatments. Maybe share wealth better?

All, or at least the large majority of technological advancements are for the rich for starters when it doesn't work that well, then it becomes available to the middle class and it works better and are cheaper and then it becomes super cheap and ubiquitous, basically everyone has accass to it.

I don't know your age but mobile phones was like that crazy expensive and only worked in some cities. Smartphones were similar and many medical treatments are the same, cardio vascular treatments like stents and bypass are done on the regular today for example.
