Lacking a college education my simplistic take on the cave Leaving out the need for going to the bathroom & interacting with others. It's easy to understand knowledge was limited to what could be seen in front of them. The conclusion was probably the basis for don't shoot the messenger. Relating that to present day the closest IMO would be the bulk of mainstream media presenting shadows & constant negativity. The light being shown would be issues affecting all Americans & the world in general. Issues like trade imbalance, illegal entry to America, border security, manufacturing jobs vs service jobs. Trump like the prisoner that returned is forcing the population to think about those issues. The rest of the world adjusting to a change in what was always before their eyes. Similar to the conclusion of The Cave. MSM is in effect shooting Trump the messenger.
