How are the adults portrayed as liars in the first five chapters of The Boy in the Striped Pajamas by John Boyne?

In this Educator's opinion, the best example of a lie is in Chapter 5 of The Boy in the Striped Pajamas.  Bruno's father is talking with his disgruntled son about the "importance of his new position" here outside of the concentration camp.  At this point, the young Bruno is very upset because everything is dreary and there is no one to play with.  When Bruno asks who the people are in "the striped...

In this Educator's opinion, the best example of a lie is in Chapter 5 of The Boy in the Striped Pajamas.  Bruno's father is talking with his disgruntled son about the "importance of his new position" here outside of the concentration camp.  At this point, the young Bruno is very upset because everything is dreary and there is no one to play with.  When Bruno asks who the people are in "the striped pajamas," Bruno's father says the following:

They’re not people at all ... at least not as we understand the term. ... You have nothing whatsoever in common with them.

This is a lie.  The people behind the fence are Jewish people.  Bruno does, in fact, have things in common with them and proves this in his eventual friendship with Shmuel.  The lie Bruno's father tells is incredibly significant in that it is truly a result of Nazi propaganda.  The German people under the Nazi regime are taught that Jewish people are "not people at all" and are little better than animals.  His father admits this is "not as we understand the term" because Nazis believe that the Aryan race is far superior to any other.
