Perhaps people are seeing that, on the one hand, large-scale problems (global warming, global pandemics, global economic boom-and-bust cycles, etc.) are having real consequences for individuals, and on the other hand, they cannot be resolved by simple independent action (because if they could, we'd be seeing trends of improvement, not worsening).
There's a crisis of faith in the reasoning capacity of the common individual. People have traditionally turned to institutional power when individuals seem less trustworthy.
