^Because the benefits of far smaller steps to the direction of enhancing the span of human-life already are only enjoyed by small (albeit not quite as tiny) minorities: the average life-span is far smaller than it is in the countries of the West.
I see no reason at all to think that if we have the ability to live decades longer than now, this will somehow benefit those who already die on average even more decades younger than most of the people in our own countries. On the contrary it seems pretty probable that even in the West, not many would be able to pay for those breakthrough technologies which would make life last longer. Thus only a small minority of the small minority of western people will benefit.
And if you turn this into a tech about actual "immortality", then even less will realistically be able to use it.
