I watched about half the lecture since it wasn't going anywhere I found eye opening. I wrote something in the thread earlier touching on the vague collective feeling of security americans cling to, even with knowledge of how corrupt the system is, but deleted it. The upstairs-downstairs security of the serfs provided by divinely-ordained overlords theory isn't particularly new, if that's the part of the lecture you're referring to.
I mean, it's as obvious as the double-edged sword of 'first responder' worship in america, where on one hand the system cultures a publicly unassailable constituency (primarily the police) to be held in the highest regard within every tragedy covered by the media, while simultaneously they're increasingly militarized and their transgressions against the public they serve are mostly forgiven. All because they're the most useful of idiots.
Take that viewpoint into polite conversation and see what happens. It's pretty much the same as the overlord-serf-security angle -- people may realize it on some level but they don't want to cop to it. Internet addiction, climate collapse ... same thing.
