Esquire's article Greetings From Idiot America is one of the best-written diatribes on the decline of American society that I've ever read. I've chosen a couple of passages that I found most interesting, but the entire, somewhat long read is well worth it:

The Gut is the basis for the Great Premises of Idiot America. We hold these truths to be self-evident:
1) Any theory is valid if it sells books, soaks up ratings, or otherwise moves units.
2) Anything can be true if somebody says it on television.
3) Fact is that which enough people believe. Truth is determined by how fervently they believe it.

This is how Idiot America engages the great issues of the day. It decides, en masse, with a thousand keystrokes and clicks of the remote control, that because there are two sides to every question, they both must be right, or at least not wrong. And the poor biologist's words carry no more weight than the thunderations of some turkey-neck preacher out of the Church of Christ's Own Parking Facility in DeLand, Florida. Less weight, in fact, because our scientist is an "expert" and, therefore, an "elitist." Nobody buys his books. Nobody puts him on cable. He's brilliant, surely, but his Gut's the same as ours. He just ignores it, poor fool.

The rest of the world looks on in cockeyed wonder. The America of Franklin and Edison, of Fulton and Ford, of the Manhattan project and the Apollo program, the America of which Einstein wanted to be a part, seems to be enveloping itself in a curious fog behind which it's tying itself in knots over evolution, for pity's sake, and over the relative humanity of blastocysts versus the victims of Parkinson's disease.

"You don't need to be credible on television," explains Keith Olbermann, the erudite host of his own show on MSNBC. "You don't need to be authoritative. You don't need to be informed. You don't need to be honest. All these things that we used to associate with what we do are no longer factors.

"There is an entire network [the Fox News Channel] that bills itself as news that is devoted to reinforcing people's fears and saying to them, 'This is what you should be scared of, and here's whose fault it is,' " Olbermann says. "And that's what they get--two or three million frustrated paranoids who sit in front of the TV and go, 'Damn right, it's those liberals' fault.' Or, 'It's those--what's the word for it?--college graduates' fault.' "

"Somewhere along the line, we stopped rewarding intelligence with success and stopped equating intelligence with success," Olbermann says. We're all in the bar now, where everybody's an expert, where the Gut makes everyone so very sure. All opinions are of equal worth. No voice is more authoritative than any others; some are just louder. Of course, the problem in the bar is that sooner or later, for reasons that nobody will remember in the clear light of the next morning, some noisy asshole picks a fight. And it becomes clear that the rise of Idiot America has consequences.
