I think this idea is naïve. The progress of medicine have never been perfectly distributed, but they are mostly widely available after a relatively short time.

I think this idea is naïve. The progress of medicine have never been perfectly distributed, but they are mostly widely available after a relatively short time. I don't see why any process of life extension would not follow the same pattern. The power of wealthy/powerful individuals is directly related to how many less wealthy individuals are willing to work for them in exchange of money/power. A rising tide is lifting all the boats. If you take the opposite stance, would reducing humanity lifespan be a good thing to fight inequality? I think this is the opposite, regardless of income/wealth/power distribution, at the individual level, a longer lifespan would increase freedom and real wealth.
