Are post-industrial modern societies “doomed” to a diminishing quality of life?

Quality of life, and monetary power in Spain, as well as other occidental countries, has been "on the down" (in some metrics) for quite some years or even decades now. A lot of people in politics seem to use this kind of situations to blame something or someone in particular, but in some ways, I see it as a natural evolution after rapid industrialization, although I am no expert.

Is this something inevitable, or are there ways to change the trend?
