This article, from what appears to me to be a Ron Paul type libertarian source, makes reference to comments by a former World Bank official and a study of the inter-relationships of top economic players to reveal what keen left observers have known for a long time: top financial institutions lie at the core of a web of financial and industrial corporations whose power is highly concentrated, so much so, that they have taken a large measure of control of governments and the media.
A former insider at the World Bank, ex-Senior Counsel Karen Hudes, says the global financial system is dominated by a small group of corrupt, power-hungry figures centered around the privately owned U.S. Federal Reserve. The network has seized control of the media to cover up its crimes....While such libertarians can see the unfairness all around them that the capitalist system has wrought, they have an undying faith in the system itself. Thus, they essentially say "keep the faith"--we only need to reform the system by a return to a mostly mythical past in which the economy was characterized by small competing industrial units using "precious metals" as its currency.
After reading this, you may want to read an alternative take on what makes the world tick posted on the Occupy Oakland Media collective's website entitled, "I Want to Believe". Although they don't disagree with the phenomenon of power concentration, essentially their message is "it's the [economic system], stupid!"
