What do you mean by "manufactured consent for each other the whole time"? I'm familiar with the Noam Chomsky book Manufacturing Consent, but this book was about the dynamics that shape coverage decisions in mass media, not some concrete process which Person X could perform "for" Person Y.

I also struggle to see how it can be that different Presidents with often directly contradictory policies could both be serving the same ruling class interests. If the funding rules for scientific grants are changing, and defenders of the old rules argue that this is a terrible change that will cause huge problems, how can it be that both the old rules and the new rules serve the same interests?
