I think of Herr Hauser as the Beseiged Teutonic Knight.
He is a true White Martyr.
Let me explain,there are Red Martyrs like Bruno ,who are physically annihilated for daring to follow the path of truth and then there are White Martyrs like our beseigned Teutonic Knight who has been forced to live a life of pain and suffering because he refuses to bow and scrape in front of employers, though he is more capable intellectually than most of the employees in the US.
But the employers demands bowing and scraping in addition to official duties and so they have turned him into the White Martyr.
