This piece by Angelo Codevilla, America's Ruling Class -- And the Perils of Revolution, is worth reading in its entirety. Codevilla's thesis is that the class divide in America is not left/right, not Democrat/Republican, but ruling and the ruled (what he calls the "country class"). This is reminiscent of Virginia Postrel's "The Future and Its Enemies", where she defines the divide as stasist/dynamist.

I detect a level of pro-creationist/anti-evolution bias, in that he uses terms like "Darwinism" instead of "evolution" or "evolutionary theory". I also detect a level of anti-science bias in general, but with things like Climategate undermining the seriousness of scientific endeavor, I can't blame him. Aside from those points, I thought the work was excellent.

I would like to quote relevant sections, but every paragraph has at least one quotable sentence, which make my task difficult. All emphasis is added.

... Republican and Democratic office holders and their retinues show a similar presumption to dominate and fewer differences in tastes, habits, opinions, and sources of income among one another than between both and the rest of the country. They think, look, and act as a class.

Never has there been so little diversity within America's upper crust. Always, in America as elsewhere, some people have been wealthier and more powerful than others. But until our own time America's upper crust was a mixture of people who had gained prominence in a variety of ways, who drew their money and status from different sources and were not predictably of one mind on any given matter.

Today's ruling class, from Boston to San Diego, was formed by an educational system that exposed them to the same ideas and gave them remarkably uniform guidance, as well as tastes and habits. These amount to a social canon of judgments about good and evil, complete with secular sacred history, sins (against minorities and the environment), and saints.

What really distinguishes these privileged people demographically is that, whether in government power directly or as officers in companies, their careers and fortunes depend on government.

If, for example, you are Laurence Tribe in 1984, Harvard professor of law, leftist pillar of the establishment, you can "write" your magnum opus by using the products of your student assistant, Ron Klain. A decade later, after Klain admits to having written some parts of the book, and the other parts are found to be verbatim or paraphrases of a book published in 1974, you can claim (perhaps correctly) that your plagiarism was "inadvertent," and you can count on the Law School's dean, Elena Kagan, to appoint a committee including former and future Harvard president Derek Bok that issues a secret report that "closes" the incident. Incidentally, Kagan ends up a justice of the Supreme Court. Not one of these people did their jobs: the professor did not write the book himself, the assistant plagiarized instead of researching, the dean and the committee did not hold the professor accountable, and all ended up rewarded. By contrast, for example, learned papers and distinguished careers in climatology at MIT (Richard Lindzen) or UVA (S. Fred Singer) are not enough for their questions about "global warming" to be taken seriously. For our ruling class, identity always trumps.

No, our ruling class recruits and renews itself not through meritocracy but rather by taking into itself people whose most prominent feature is their commitment to fit in. The most successful neither write books and papers that stand up to criticism nor release their academic records. Thus does our ruling class stunt itself through negative selection. But the more it has dumbed itself down, the more it has defined itself by the presumption of intellectual superiority.

Hence more power for the ruling class has been our ruling class's solution not just for economic downturns and social ills but also for hurricanes and tornadoes, global cooling and global warming. A priori, one might wonder whether enriching and empowering individuals of a certain kind can make Americans kinder and gentler, much less control the weather. But there can be no doubt that such power and money makes Americans ever more dependent on those who wield it.

Laws and regulations nowadays are longer than ever because length is needed to specify how people will be treated unequally. For example, the health care bill of 2010 takes more than 2,700 pages to make sure not just that some states will be treated differently from others because their senators offered key political support, but more importantly to codify bargains between the government and various parts of the health care industry, state governments, and large employers about who would receive what benefits (e.g., public employee unions and auto workers) and who would pass what indirect taxes onto the general public.

Nowadays, the members of our ruling class admit that they do not read the laws. They don't have to. Because modern laws are primarily grants of discretion, all anybody has to know about them is whom they empower.

That's only halfway through the article. There's a lot more. Read the whole thing.
