The most basic reason as to why more people don't complain about being ruled by the rich and the politically connected in America is the fact that America is by far the richest country in the world as demonstrated by its ranking as #1 in Gross Domestic Product (GDP), to which China a country that is approximately the same size as the United States in land area, but has four times the amount of peoples, has in whole utilizing nominal GDP as the measure not even 60% of America's GDP. This means, therefore, that in essence, virtually everyone in America that doesn't live in some forlorn town that is well off the beaten track, has seen or felt in person the wealth of America in its buildings, its infrastructure, its stores, its clothes, its vehicles, its hi-technology electronics, and the like. In America, you don't have to be rich in order to appreciate how rich that America is and at least have some of that wealth trickle down to you. However, in America, you do have to be rich in order to appreciate what money can really do for you, as the people that run this country in all of its many aspects, are either super-rich or powerfully connected or both.
The fact of the matter is, money and power are addictive, to wit, there are very few that once obtaining these things, have a willingness to let any of it go. What you find in actuality, is that those that have the wealth and the political influence, want more of it, and will make it their mission to keep it this way. This means, by definition, since there are so few that are so wealthy, and so many that are not, that the elite few, make it their policy to join together, in the overriding vision, that money and the lust for money trump over all else. Therefore, the plutocrats of America have an abiding interest in seeing that their offspring go to the same schools as other super-rich children so that they can intermarry, and further that they will later take interchangeable directorship positions in their respective corporations, and as always, make sure that they as the elite have special rights and privileges unknown to the likes of the common man.
The playing field in America has never been equal, and never will be. While this is a country of laws, it is also a truism that in America, you get all the justice that you can pay for. When it comes to taxation, the rich are adept at working every conceivable angle, utilizing too the most influential lobbyists, to beat back anything that would take from them, their almighty fortune. Our tax codes and laws are reams upon reams of incomprehensible laws, navigational only by those in the know, and always in the end, providing a convenient escape hatch for those that are connected.
The Federal Reserve, despite its name, is a private banking consortium, it certainly doesn't answer to the people, as its true master is the rich and powerful. As President Garfield stated, "He who controls the money supply of a nation controls the nation." I do submit, I can't think of any position within America, that has within its hands more primal power, than those that print and distribute the Federal Reserve notes, that we use day-to-day to conduct business, pay bills, buy goods, and the like. Money and the timely access to money, exerts terrible power and influence of one man over another, the power to buy a favor, to corrupt an official, to destroy an individual, and in conjunction with others of like principles, to rule America.
