I hardly ever agree with Zd542 but he is most certainly
correct about AL not missing much.
The professors point was that Americans are anti-intellectual which is generally true. I remember eating at a table at the Free University of Berlin, when a fellow American said to a German student jokingly. "if you're so smart why aren't you rich?" The half dozen German students had zero idea what he meant and they all spoke English well.
The Harvard prof also dragged me over to a window, parted the blind and said in Russia I could look out see the KGB agent watching my apartment, Americans have a better system, they carry their own KBG agent around in their heads.
