Here is an excerpt:
Many people, such as philosopher John Harris and those in the Pew Center survey, worry that life extension would be available only to the rich and make existing inequalities even worse.
Indeed, it is unjust when some people live longer than the poor because they have better health care. It would be far more unjust if the rich could live several decades or centuries longer than anyone else and gain more time to consolidate their advantages.
Some philosophers suggest that society should prevent inequality by banning life extension. This is equality by denial – if not everyone can get it, then no one gets it.
However, as philosopher Richard J. Arneson notes, “leveling-down” – achieving equality by making some people worse off without making anyone better off – is unjust.
Indeed, as I argue in my recent book on life extension ethics, most of us reject leveling-down in other situations. For example, there are not enough human organs for transplant, but no one thinks the answer is to ban organ transplants.
Moreover, banning or slowing down the development of life extension may simply delay a time when the technology gets cheap enough for everyone to have it. TV sets were once a toy for the wealthy; now even poor families have them. In time, this could happen with life extension.
