This essay by Bill Moyers, a left winger and former LBJ press secretary who is almost 80 years old, is interesting. It has the usual leftist slant on the topic but also includes many good observations.
There is the visible government situated around the Mall in Washington, and then there is another, more shadowy, more indefinable government that is not explained in Civics 101 or observable to tourists at the White House or the Capitol. The former is traditional Washington partisan politics: the tip of the iceberg that a public watching C-SPAN sees daily and which is theoretically controllable via elections. The subsurface part of the iceberg I shall call the Deep State, which operates according to its own compass heading regardless of who is formally in power. 
Moyers had a significant role to play in the early stages of this administrative state.
Failure to recognize the distinction between the way in which the Department of the Army operates and the standing operating procedures of military organizations in the field has frustrated generations of field soldiers, who have taken for granted the necessity for tight management at the top, known to them as unity of command.This struggle for executive control within the Army has
taken place during a period of increasingly centralized authority over individual and corporate activities throughout American life.
Moyers has more of a role here than he admits. After some nonsense about Republican “obstructionism,” he says this:
Despite this apparent impotence, President Obama can liquidate American citizens without due processes, detain prisoners indefinitely without charge, conduct dragnet surveillance on the American people without judicial warrant and engage in unprecedented — at least since the McCarthy era — witch hunts against federal employees (the so-called “Insider Threat Program”). Within the United States, this power is characterized by massive displays of intimidating force by militarized federal, state and local law enforcement.
I think it is interesting to see that the left, certainly Moyers territory, sees this.
During the time in 2011 when political warfare over the debt ceiling was beginning to paralyze the business of governance in Washington, the United States government somehow summoned the resources to overthrow Muammar Ghaddafi’s regime in Libya, and, when the instability created by that coup spilled over into Mali, provide overt and covert assistance to French intervention there. At a time when there was heated debate about continuing meat inspections and civilian air traffic control because of the budget crisis, our government was somehow able to commit $115 million to keeping a civil war going in Syria and to pay at least £100m to the United Kingdom’s Government Communications Headquarters to buy influence over and access to that country’s intelligence. Since 2007, two bridges carrying interstate highways have collapsed due to inadequate maintenance of infrastructure, one killing 13 people. During that same period of time, the government spent $1.7 billion constructing a building in Utah that is the size of 17 football fields. This mammoth structure is intended to allow the National Security Agency to store a yottabyte of information, the largest numerical designator computer scientists have coined. A yottabyte is equal to 500 quintillion pages of text. They need that much storage to archive every single trace of your electronic life.
Government life is typically not some vignette from an Allen Drury novel about intrigue under the Capitol dome. Sitting and staring at the clock on the off-white office wall when it’s 11:00 in the evening and you are vowing never, ever to eat another piece of takeout pizza in your life is not an experience that summons the higher literary instincts of a would-be memoirist. After a while, a functionary of the state begins to hear things that, in another context, would be quite remarkable, or at least noteworthy, and yet that simply bounce off one’s consciousness like pebbles off steel plate: “You mean the number of terrorist groups we are fighting is classified?” No wonder so few people are whistle-blowers, quite apart from the vicious retaliation whistle-blowing often provokes: Unless one is blessed with imagination and a fine sense of irony, growing immune to the curiousness of one’s surroundings is easy. To paraphrase the inimitable Donald Rumsfeld, I didn’t know all that I knew, at least until I had had a couple of years away from the government to reflect upon it.
The IRS bureaucrat begins to see that the Tea Party is a threat to his pension and continued nice life. That, of course, is not what Moyers is concerned about.
The Deep State does not consist of the entire government. It is a hybrid of national security and law enforcement agencies: the Department of Defense, the Department of State, the Department of Homeland Security, the Central Intelligence Agency and the Justice Department. I also include the Department of the Treasury because of its jurisdiction over financial flows, its enforcement of international sanctions and its organic symbiosis with Wall Street. All these agencies are coordinated by the Executive Office of the President via the National Security Council. Certain key areas of the judiciary belong to the Deep State, such as the Foreign Intelligence Surveillance Court, whose actions are mysterious even to most members of Congress. Also included are a handful of vital federal trial courts, such as the Eastern District of Virginia and the Southern District of Manhattan, where sensitive proceedings in national security cases are conducted. The final government component (and possibly last in precedence among the formal branches of government established by the Constitution) is a kind of rump Congress consisting of the congressional leadership and some (but not all) of the members of the defense and intelligence committees. The rest of Congress, normally so fractious and partisan, is mostly only intermittently aware of the Deep State and when required usually submits to a few well-chosen words from the State’s emissaries.
This is what some of us refer to as The Ruling Class.
There are now 854,000 contract personnel with top-secret clearances — a number greater than that of top-secret-cleared civilian employees of the government. While they work throughout the country and the world, their heavy concentration in and around the Washington suburbs is unmistakable: Since 9/11, 33 facilities for top-secret intelligence have been built or are under construction. Combined, they occupy the floor space of almost three Pentagons — about 17 million square feet. Seventy percent of the intelligence community’s budget goes to paying contracts. And the membrane between government and industry is highly permeable: The Director of National Intelligence, James R. Clapper, is a former executive of Booz Allen Hamilton, one of the government’s largest intelligence contractors. His predecessor as director, Admiral Mike McConnell, is the current vice chairman of the same company; Booz Allen is 99 percent dependent on government business. These contractors now set the political and social tone of Washington, just as they are increasingly setting the direction of the country, but they are doing it quietly, their doings unrecorded in the Congressional Record or the Federal Register, and are rarely subject to congressional hearings.
Remove some of the obligatory left wing rhetoric and I agree with this completely. Read the rest.
In 2013, General David Petraeus joined KKR (formerly Kohlberg Kravis Roberts) of 9 West 57th Street, New York, a private equity firm with $62.3 billion in assets. KKR specializes in management buyouts and leveraged finance. General Petraeus’ expertise in these areas is unclear. His ability to peddle influence, however, is a known and valued commodity. Unlike Cincinnatus, the military commanders of the Deep State do not take up the plow once they lay down the sword. Petraeus also obtained a sinecure as a non-resident senior fellow at the Belfer Center for Science and International Affairs at Harvard. The Ivy League is, of course, the preferred bleaching tub and charm school of the American oligarchy. 
Exactly. Think about global warming and energy policy, matters Moyers neglects.
