Treatments to repair the root cause cell and tissue damage that leads to degeneration will be mass-produced infusions when realized, since everyone ages due to the same underlying reasons. They will not be very expensive, their price trajectory looking like that for drugs today, assuming the regulatory environment remains consistent over the decades ahead. Ultimately they will be as cheap as older medications are today. But to get to that point you have to start by creating the treatments.
If we ever got to a point where some people had greatly extended their lives and/or eliminated death for themselves whilst others still faced premature death from a basic lack of the necessities of life, well then, we'd be an even more narcissistic race than I originally thought.
We all shouldn't simply sit by idling until all the basic problems are fixed. Solving the "basic necessities" problem might be more economic related or come down to creating technology to create cheap, clean energy, for example.

We spend billions on bottled water:

Shouldn't we drink tap water and use the money saved to get water to people in need?
Bill Gates had this to say: "It seems pretty egocentric while we still have malaria and TB for rich people to fund things so they can live longer. It would be nice to live longer though I admit"
Not the authoritative word on the issue but interesting considering he has the opportunity to do either yet is focussing on malaria, TB etc

By doing really difficult and expensive medical research over decades, we will discover many things that help many of the 7 billion people, increasing to 9 billion, on the planet. Knowledge isn't something that stays locked up forever, and which only rich people have access to it.
Age related research will benefit over 10 billion people in this century. Most of us will get old.
