Trust is what maintains societal institutions. Trust in the institutions. Unfortunately, trust has been eroded significantly all around the world. I suspect that this erosion was intentional, the result of highly effective propaganda campaigns being waged by different governments against each other. Ironically, these campaigns are so effective at eroding trust because of the efficiencies that our technological advances have contributed to their prosecution.
Personally, I'm not sanguine that trust will return. Couple these professional manipulation campaigns with the very real degradation of professionalism within many societal institutions and you can see the very clear challenges ahead. Without trust, you just can't get there. And in the face of these manipulation campaigns, without professionalism, you'll be challenged to get any level trust back.
It's just too easy right now for these campaigns to point out the lack of professionalism. (BTW, we should be shining a light on corruption etc. I'm just pointing out what I see as a problem with building trust.)
