Teaching is one of the traditional avenues out of the working class. Which also means relatively (compared to other people on the same income) working class values.
Although does not sound as if that was the case at least for Palin's mother's family.
Oh, also: The author is giving way to much credit to Nixon's maudlin "I'm not a millionaire's son" shtick. He wasn't that unpalinlike either.
the profession of Palin's uncle has little to nothing to do with how Palin grew up....as to the profession of her mother and father, maybe I don't understand the definition of the working class as the term "working” describes many people of differing income levels…to me it simply means those who must work for their living.
