Why according to the commandant of the labor camp (Amon Goeth) is "today history?"

Goeth says this to his soldiers before the liquidation of the ghetto. It is meant as inspiration for destruction and violence. This quote is one of the only of its kind in the movie, for it expresses the resentment against Jews and the reasons for the desire to remove them from society. Nazis resented the success the Jews experienced, especially since the Jews did not integrate themselves into Polish or German society (partially due to negative attitudes toward them).
