George Santayana

By irreducibly complex I mean a single system composed of several well-matched, interacting parts that contribute to the basic function, wherein the removal of any one of the parts causes the system to effectively cease functioning.

Finding a 'sacrificial lamb' on whom to tag blame for complicated problems is an important instrument in the toolkit of politicians, because it deflects blame for the nation's economic woes away from their own regulatory lapses, economic mismanagement and coddling to labor unions.
