And I’m saying if you do not look at the root cause, but continue to look at the symptoms, the problem will never be resolved.
Look at my posting #168! Aren't twenty-some-odd root causes enough for you?
On the other hand, if you insist upon reducing everything down to a single, ultimate cause - you'll get a truism so tautological that it doesn't explain anything. Something like, "People are just plain bad!" Or, by analogy: In the case of the Japanese bombing of Pearl Harbor, "Well, the root cause was that the Japanese military wanted / felt it necessary to bomb P.H.!"
My identification of 20-some-odd factors goes a lot farther towards helping us establish a possible course of action than just observing, "Humanity is flawed!"
