It is an important thing to say. Among the less attractive aspects of human nature are a fixation with what is rather than what can be, the tendency to limit the definition of success and desired outcomes to whatever the best of the present options might be, and a burning desire to tear down those who have more than you rather than work to create more for everyone. Even in an age of rapid, radical change driven by advancing technology, the vast majority of people focus entirely on the distribution of present assets and opportunities, giving little to no thought to the much larger set of assets and opportunities that we could create for tomorrow. You see this in the vastly greater attention given to any evidence for distributions and correlations in life expectancy between populations today, and the tiny amount of attention and support given to the production of rejuvenation therapies to greatly increase life for everyone at a modest cost. Given the realization of SENS rejuvenation treatments, the first of which are already under development in startup companies, and most of which will take the form of comparatively low-cost, mass-produced infusions, ten year variations in longevity due to lifestyle choices or access to medicine will be swamped, made irrelevant and small.
