" What is the actual link between material consumption and objective and subjective quality of life once the basic needs for food, clothes, shelter, and mobility are well satisfied? Going from material misery to modest material comfort will make many things in life better but, obviously, the link is not an endless escalator. But if so, where is the saturation point? Can such a level actually be quantified in a meaningful way? These questions must be asked even if there are no easy answers, mainly because of the situation that is the very opposite of the material poverty outlined at the beginning of this section: too many people live in the condition of material excess and this does not endow them with a higher physical quality of life than that enjoyed by moderate consumers and it does not make them exceptionally happy. At the most fundamental level, the question is about the very nature of modern economies. All but a tiny minority of economists (those of ecological persuasion) see the constant expansion of output as the fundamental goal. And not just any expansion: economies should preferably grow at annual rates in excess of 2%, better yet 3%. This is the only model, the only paradigm, and the only precept, as the economists in command of modern societies cannot envisage a system that would deliberately grow at a minimum rate, even less so one that would experience zero growth, and the idea of a carefully managed decline appears to them to be outright unimaginable. The pursuit of endless growth is, obviously, an unsustainable strategy (Binswanger, 2009), and the post-2008 experience has shown how dysfunctional modern economies become as soon as the growth becomes negligible, ceases temporarily or when there is even a slight decline: rising unemployment, falling labor participation, growing income inequality, and soaring budget deficits.
