The fact that growth is really the only way. If you think about it, everything we achieved has been through growth (i.e. how China managed to bring millions from below the poverty line in few decades). We face enormous challenges (i.e. 7 billion people on the planet), without growth we are pretty much doomed. So, it's not so much about confidence, I think is rather hope for us as a species.
