I'd say there is an even deeper layer of memetics. What I'm referring to is what is discussed in Metal Gear Solid 2: Sons of Liberty and Ghost in the Shell: Stand Alone Complex. There is no grand scheme behind how people's biology work. It's just genetics. You can influence genetics. But nobody can control it. I've repeatedly stated the impossibility of any global conspiracy. What we actually have is constant attempts at global conspiracy. The golden age was supposedly when wisdom was treated as the highest ide and the central root/trunk of the society that hold the branches. Later it because leaders/heroes/warriors etc. Obviously these things included some level of violence. We are sort of valuing money as the centerpiece of society but we are merely transitioning to something worse. We are transitioning to destruction of value itself in an atlas Shrugged-esque future. This is far worse than violence or vanity and all of these are in the memetics of the society.
