What is the meaning of ‘sustaining narrative’ in this text? Does it mean ‘the narrative that we have had for a long time’, ‘the narrative that is entrenched for us’? I know the meaning of narrative and sustaining, but it seems this is a jargon in humanities and social sciences, if I am not wrong. Also, I have seen ‘suitability narrative’ which I think is something else.
“Every culture, every society, clings to a myth by which it lives. Ours is the myth of growth. For as long as the economy continues to expand, we feel assured that life is getting better. We believe that we are progressing – not just as individuals but as a society. We convince ourselves that the world tomorrow will be a brighter, shinier place for our children and for their children. When the opposite happens, disillusionment beckons. Collapse threatens our stability. Darkness looms on the horizon. And these demons – real as they may be in an economy dependent so entirely on growth – are rendered even more powerful by the loss of faith in our core sustaining narrative. The myth of growth.” (Excerpt From Post Growth Jackson, Tim)
