Henry Louis Gates

People are afraid, and when people are afraid, when their pie is shrinking, they look for somebody to hate. They look for somebody to blame. And a real leader speaks to anxiety and to fear and allays those fears, assuages anxiety.

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.
