The masses must be fed.  Their anger stoked.  The money rolls in.  Perfect!
The poor victims, though, like my brother-in-law, have no clue about the ponzi-like scheme in which they participate.  No clue.  They think it is a reality show.  They believe what the hucksters are pitching.  In fact, that is why the corporate sponsors love this audience- it will 'buy' anything. Gullibility incarnate.
If my brother-in-law hears it on the radio, it is true.  Really.  Absorbed like a ShamWow.  I must give him some slack, though, that I will not give to younger right-wingers.  As he is in his 70's, he grew up with radio news when the newsmen reported factual information.  He learned to trust the radio broadcasters.
The younger group, the 20 and 30-something, on the other hand, surely must know that people like Limbaugh, Hannity, Savage, Beck and others are right-wingers just like themselves, not middle of the road, honest newsmen.  Or do they?
Whatever, old or young, the radio and TV stations and the personalities are making a fortune pimping their audience with the spice, hate and emotional jargon that seems to 'satisfy' their audience.  Pimps, prostitutes, and johns.  A perfect match.
"Hey, mister, want to hear something about Nancy Pelosi...?"
