The varying conditions found in the concentration camps of Night and the internment camps of Farewell to Manzanar are rooted in the differing end goals of the horribly oppressive government of the US and the horribly oppressive government of Germany and the Nazi parties of its allied countries.
The Nazi party had launched a campaign of total extermination against Jewish people across Europe, and as such, the concentration camps reflected this end goal. Millions of Jews, as well as thousands of Roma people, LGBTQ people, mentally ill people, homeless people, political dissidents, and others, were kidnapped and held prisoner in concentration camps. At those camps, Nazi soldiers executed, beat, and tortured people, while others died from starvation, disease, and labor. The people who survived the concentration camps had to endure forced labor, inadequate food and inadequate shelter, exposure to the cold, many forms of torture, witnessing mass murders and torture, separation from loved ones, and the other horrors of imprisonment.
Farewell to Manzanar describes the oppression and torture Japanese and Japanese-American people faced as they were forced into interment camps during WWII. The US government kidnapped over 120,000 people of Japanese ancestry from their homes and held them prisoner in camps where they suffered inadequate food, inadequate shelter, confinement, familial separation, torture, beatings, exposure to the elements, forced labor, and again the general horrors of being held prisoner. Because the end goal of the United States was not to exterminate these folks, but to violently imprison them while they dropped a bomb over Nagasaki and Hiroshima, killing over 200,000 Japanese people, the internment camps did not exactly mirror the deaths camps of the Nazis. However, both were horrible concentration camps that operated from differing goals of oppressive states.
