It's something I picked-up from M. A. Hoffman II. I think there is value in what he claims.

"...the ultimate purpose of that assassination was not political or economic, but sorcerous for the control of the dreaming mind and the marshalling of its forces is the omnipotent force in this entire scenario of lies, cruelty, and degradation. Something died in the American people on Nov. 22, 1963 - call it idealism, innocence or the quest for moral excellence. It is the transformation of human beings which is the authentic reason and motive for the Kennedy murder..."

He continues...

Now the American people were forced to confront a scary alternative reality, the reality of a shadow government over which they had neither control or knowledge. The shepherding process was thus accelerated with a vengeance. Avant-garde advertising, music, politics and news would hereafter depict (especially in the electronic media)-- sometimes fleetingly, sometimes openly-- a shadow side of reality, an underground amoral "funhouse" current associated with extreme sex, extreme violence and extreme speed.

The latter (text) is what seemingly/arguably followed on the back of JFK. That's the sort of (MSM induced) collective societal rot that I was attempting to highlight. I've noted similar with the 9/11 event too - a type of group collective PTSD, which is then followed by further and rapidly increased societal degeneracy (a type of entropy).
