Arbeit macht frei:

The entrance gate to Auschwitz reads "Work makes one free." The labor camps at Auschwitz used the slave labor of Jews, political prisoners, Roma(Gypsies). More than 1.5 million people were killed through gassing, starvation, sickness, and torture in Auschwitz, Nazi Germany's largest concentration camp.

Is not it ironic that on the biggest concentration camp(if we disregard GULAG in Siberia) there is a sign that the work frees the person. The NAZI ideology can be summurized in the difference between this
statement and the brutalities and attrocities that million people have undergone behind the gates of Auschwitz:

Although the theme about the Holocaust has been analyzed in every dimension after the World War II, I would like briefly to add the opinion that events and groups like  Die Kristallnacht,Die SS Einsaztgruppen,
Die Letzte Losung are better not to be discussed, but to be set as an alert of highest importance to the future generations.
