Angelo M. Codevilla wonders how long two-thirds of America can possibly be ruled by a well-entrenched elitist third.

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. The Boston Brahmins, the New York financiers, the land barons of California, Texas, and Florida, the industrialists of Pittsburgh, the Southern aristocracy, and the hardscrabble politicians who made it big in Chicago or Memphis had little contact with one another. Few had much contact with government, and “bureaucrat” was a dirty word for all. So was “social engineering.” Nor had the schools and universities that formed yesterday’s upper crust imposed a single orthodoxy about the origins of man, about American history, and about how America should be governed. All that has changed.

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. Using the right words and avoiding the wrong ones when referring to such matters — speaking the “in” language — serves as a badge of identity. Regardless of what business or profession they are in, their road up included government channels and government money because, as government has grown, its boundary with the rest of American life has become indistinct. Many began their careers in government and leveraged their way into the private sector. Some, e.g., Secretary of the Treasury Timothy Geithner, never held a non-government job. Hence whether formally in government, out of it, or halfway, America’s ruling class speaks the language and has the tastes, habits, and tools of bureaucrats. It rules uneasily over the majority of Americans not oriented to government.

The two classes have less in common culturally, dislike each other more, and embody ways of life more different from one another than did the 19th century’s Northerners and Southerners — nearly all of whom, as Lincoln reminded them, “prayed to the same God.” By contrast, while most Americans pray to the God “who created and doth sustain us,” our ruling class prays to itself as “saviors of the planet” and improvers of humanity. Our classes’ clash is over “whose country” America is, over what way of life will prevail, over who is to defer to whom about what. The gravity of such divisions points us, as it did Lincoln, to Mark’s Gospel: “if a house be divided against itself, that house cannot stand.”
