"The primary measure of technological progress is life expectancy. Not the stock market."

NB: Graph from Our World in Data, who underline that:

The decline of child mortality was important for the increase of life expectancy, but as we explain in our entry on life expectancy increasing life expectancy was certainly not only about falling child mortality – life expectancy increased at all ages.
Such improvements in life expectancy — despite being exclusive to particular countries — was a landmark sign of progress. It was the first time in human history that we achieved sustained improvements in health for entire populations. After millennia of stagnation in terrible health conditions the seal was finally broken.
