The guys at the top share class interests. That’s what unites them, not ideology. The ones at the top just say whatever needs to be said (whatever will benefit the plutocracy) to get to the top. But they’re not united at all. As soon as cracks appear, they turn on each other. I just don’t see this unity the OP is talking about. The problem is not that “evil is united”. The problem is that it’s too easy to propagandize vast amounts of the population when one controls the narrative through wealth and centralized media.
