I do not share this opinion! Certainly a financial ease can soften, by its environment, a sickness related to the disease, but (in the conventional system) the end is inevitable at this level of attack there. But he's a competitor and you never know!
The question is not there! You just break in an open door. Someone like him has never had to work in a dangerous atmosphere (noise, dust, chemicals, stress), he has never been exposed to industrial accidents (machine, MSD, scaffolding ...) all things which shorten the days or / and make them painful with the infirmities which ensue from them. Although I do not suspect you of using this subterfuge which consists in insisting on abstract equality before death to hide very different social realities, this kind of abusive generalization should be avoided.
Transhumanism, quite logically, seeks to reinforce these injustices by providing the privileged with immortality (which is not necessarily so desirable as that, but it is obviously not the opinion of the partisans of this ideology).
