I'm convinced successful organization of the working class shakes and worries the ruling class much more than a singular incidence of killing a CEO. So I might have argued on a different level than you meme does, but my point stands. Apart from mass media hyping this topic for views, I'm convinced the ruling class rests quite assured, that this is an isolated phenomenon - at least for now. They're just gonna up their security standards a bit and continue business as usual.
