Mr. Atcheson is correct about the MONEY factor while the "confirmation bias" is a lesser contributing factor. The nature of business within the USA, today, is almost without exception, exceptionally top-down heavy. Orders "from above" work like marching orders and anyone who wishes to keep their place in the race had better keep up.
That's why so many journalists sound like parrots. And as Robert Parry has often pointed out, regardless of the media brand name, essentially, all repeat the same memes and Talking Points.
This, on the other hand, cannot BE mentioned often enough. Intelligent minds extract from this study the realization that any analysis that purports to speak for WE, The American People, when it furthers the interests of the 1%, Establishment Powers, or the MIC... is based completely upon deception and the wish to tame people by covertly pushing them to identify with the status quo:
"And of course, as Martin Gilens and Benjamin I. Page pointed out in their landmark study on the influence of money and special interests in politics, corporations and the ultra-rich would risk losing what amounts to nearly complete control of the policies this country chooses if a candidate like Sanders won. As Gilens and Page point out:
"When the preferences of economic elites and the stands of organized interest groups are controlled for, the preferences of the average American appear to have only a minuscule, near-zero, statistically non-significant impact upon public policy."
When YOU have ZERO impact on policy making, and YOU are one of the millions also left out, how then can it be that some collective WE can be tagged with responsibility for what Special Interests & Dark Powers engineered?
P.S. Passionate analysis, Mr. Atcheson!
