Friedrich - The Most Important Character in 'Friedrich'

I think the title speaks for itself.

Friedrich to me (and I realise to a lot others) is the MOST important character in the story. I am also wondering why Hans Peter Richter did not put Friedrich himself as the narrator, and instead someone anonymous person the same age as Friedrich. He might have wanted his readers to look at the Jewish discrimination from a non-Jewish's point of view. Whichever way, Friedrich experienced all the bad times (correct me if I should be using any other tense). After all, his mother was not there to experience it and his father was hardly mentioned after he got deported. Friedrich could not go to the movies, could only sit on certain benches, could not go to the swimming pool, and lots more, all for a ridiculous, unjustified reason - he was a Jew.

So, all this proves that the main story is about Jewish discrimination in the life of a young boy growing into a young man - Friedrich. The other characters are important to the plot, but he is at the top.

Anyway, the other characters are as follows:

Important:
Narrator
Herr Resch
Herr Schneider

Not so important:
Frau Schneider
Rabbi
Helga
The Narrator's family
Frau Penk
