For the germans interviewed in the book, it seems to be true that many had read or heard about the camps or other atrocities, but (1) not the “final solution” which was not in the press and (2) there seems to be heavy desensitization from 1933-1955 when the book was written.
Aside from the tailor that had started the fire at the synagogue, the other 9 interviewees had not directly witnessed atrocities being committed, and instead focused on their personal hardships during the war.
Even though they may have been literate, the people in Mayer’s book were ignorant of the specific realities. Perhaps willfully ignorant, yes, but the nazi regime really did not give any opportunities otherwise.

not an expert, just reporting my notes from the book.
i highly recommend all americans read it, its not a long book. it feels eerily familiar, even though many circumstances are drastically different.
