The argument about Democrat versus Republican is semantical.
Both answer to the same people, as all of politics is merely a theater, and those in control will control the theater and ensure that they own both.
Both support the notion of a central bank, large debts (Reagan economists went so far as to declare that 'the national debt doesn't matter'), and slave labor via the integration of a global economy (Clinton oversaw the passage of both NAFTA and Most Favored Nation Trade Status being bestowed upon China).
There is no difference. Really. The sooner we can all agree that interjecting the idea that there is a difference, the better, as it's just a distraction.
I am not a conspiracist. I am a realist. Who really calls the shots? Those that control the money and/or the military.
This is true in any nation throughout history.
In modern times, there has been a closer and deeper nexus between commerce and military, but the nexus has always existed.
Despots, Dictators, Czars, Kings and freely elected leaders all realize that controlling military power and the means of commerce (money supply, means of production, essential goods and services) are the most powerful levers available to men. You can enslave entire populations by exercising a firm grip over these things.
So, who really does control these things in modern day America?
