I think while we can all get down about the state of the world, and all the suffering, but its important to keep perspective. No one changes these things except people like you and me. By completely ignoring these issues you do your fellow man a disservice. Buck up and face reality! Or not, hey just trying to offer a different perspective! To answer your question, I would everybody dials this stuff out to some degree. We all have different tolerances for this stuff I think, and it varies as time goes by.
