As much as people want to believe that this is a world made up of many nations, in which those nations are sovereign and thus in control of their destiny, the truth of the matter is far more nuanced and much more complex than that, along with being in a lot of ways, quite troublesome, because the bottom line is that it is money that rules the world and that money in an age in which international travel, communication, banking and business transactions are in a lot of ways seamless signifies that it is concentrated money which is the awesome force of power, that rules the roost, and therefore in the most important affairs of the state we are not ruled by our sovereign governments.
Look, it's like this, those that have money, be it personal wealth or corporate wealth, are in many a case, absolutely determined to not just keep that money, but are obsessed about enhancing it, and therefore those with money and the connections so necessary to make that money more dominant are absolutely intent upon doing whatever is necessary to increase their power and control over worldwide affairs, which is why those in the traditional highest form of power such as Presidents, Kings, and the like, along with their legislative branches, and judicial courts, have been so often "captured" by big money so that nothing is left to chance, and anybody influential and important that gets out of line, will thereby be compromised, marginalized, or eradicated.
The thing about money is that it knows not any borders. Those with mega-wealth have no loyalty to their state of residency, but rather have loyalty only to mammon. Thus, this is why the superrich from all over the world get together and coordinate their actions because they are all part of the same team, which is beyond national identities, beyond religion, beyond race, and beyond everything that would take away from the sheer value and importance of money, because they understand that money, worked appropriately with pliable political figures under their collective thumbs, will get them and continue to get them everything that they want, obviously done so at the expense of those that are basically seen as nothing much more than commoners, who are meant to be exploited.
So too, this is why those that are superrich don't care about governmental deficits and even encourage such, because they are the same ones that will be the financial beneficiaries when the global economic system collapses and thus has to be rearranged to stabilize the people and the affairs of governments, which will get rid of the "dry rot" and those that do not appropriately march to the drum roll of the superrich, all of which will allow the superrich to aggrandize and consolidate onto themselves even more power and control.
Those that are too credulous to believe that any of this is true, or that this is exaggerated need only to look at how in recent decades the concentration of worldwide wealth has become increasingly concentrated into ever fewer hands, and that in governments all over the world, the spying upon and the gathering of personal information of the people has never been more invasive, thus providing those with massive money power all the tools that they need to continue to bend the people to their will, while providing them with nothing much more than mindless circuses and just enough bread.
