During the 2012 presidential election campaign, Texas Governor Rick Perry criticized the actions of then Fed Chair Ben Bernanke. Perry argued that: "Printing more money to play politics at this particular time in American history is almost treasonous in my opinion." An article in the Wall Street Journal commented that despite Perry's remarks: " Bernanke is willing to embrace the political independence embedded in his role to do what Fed officials think the economy needs." How is "political independence" embedded in the role of Fed chair? Why did Congress initially decide to make the Fed independent of the rest of the federal government?
