Well that, and the wealthy have seized control of the MSM to propagandize the working class into believing that the rich alone can save them. Since the money holder always, "need a little more", they gravitate to fascism which promises them "a little more".
By "the most well-armed portion of the populace" I assume you mean law enforcement? It's an odd way of putting it, but it's the only interpretation that makes sense because Bubba and his fellow militia members sure as fuck aren't coming to the defense of the one percent.
