I think I can sum up the increasingly shrill right-wing's motives into one phrase: Keep the money flowing into the same pockets.
For that the benefits of the American economy continue flowing into the same pockets, there would have to be a sort of managed stagnation: as we are a naturally progressive society, the only means of preventing us from moving forward to newer technologies and ideas would be to submit our populace to a constant barrage of misinformation and dumbing-down about the real value (and existence of) of all that is available to us in the world today. This is what the right-wing is all about, and this is exactly what has been happening since decades.
Those on the economic recieving end of the above are the most silent players in the same story. The loudest and most shrill pundits of the right-wing agenda only feed off these: most of the feeders a) see themselves as being one of the 'well-connected' or 'privileged elite' or b) are getting some sort of financial support for their 'points of view' that benifits the financial supporter or c) see themselves as the 'enlightened leaders' over, to the benifit of the leaders, an optimally mindless society (message: "here's what you should think") or d) a mix of any of the above. In all cases, the goal for all the above is: keeping things exactly as they are.
