So why is trust in so many elite institutions collapsing at the same time? There are three key, somewhat overlapping, reasons: inequality of accountability (certain people are being punished for wrongdoing while others get a leave pass); twilight of elites and authority (the digital age is flattening hierarchies and eroding faith in experts and the rich and powerful); and segregated echo chambers (living in our cultural ghettoes and being deaf to other voices).
