You may identify it by looking into the split in the governance of the United States (I presume that is what you mean by 'America'). There are two governments in the United States, one is the Federal Reserve bank that controls the monetary policies like interest rates. Another is comprised of the Legislative, Executive and Judiciary. The Fed is insulated from politics. The President of the United States has no say on monetary policy. He cannot order minting of US coins without the approval of the Fed, as President Kennedy found out. Now America is under the thumb of corporate America, all because it created the corporation as another legal personality that has grown so big that it can produce a president of America. You cannot sue in court the chairman of the Fed if you disagree with his policies. You have to sue the Fed, and the chairman will stay even if the Fed were proven guilty. The corporation has another personality. A corporate drug maker was sued for making and marketing a painkiller. This corporation spent over 4 billion dollars in litigations and medications of victims of the drug. But the chairman of the corporation and the board members remained. They are untouchable as persons comprising the board. The budget of a multinational is even bigger than the budget of one country in Europe. One of the reasons why the Eurodollar was set up is to compete, in terms of budgets, with the corporations of America. No one nation in Europe can match the budget of a computer maker corporation in America.
The anti-trust laws might have dealt with the problems posed by corporations (overlapping directorship of corporations, identical bids for projects in government with one selected by coporations as winner).But the power gained by the Fed might prove as durable as the Vatican.
