If we're getting into the things textbooks tell us, our government serves by the will of the people. Top-down media control doesn't really jive with this.
If we go by the Bloch definition of the nobility, the clergy, and the peasantry bound by manorialism, swap each out with a modern-day group (military-industrial complex [of which SV is an offshoot], clergy, media/entertainment, and the general public), and you can still make out the same old constellation.
