I don't disagree with him about anything except the forced labor part. Though essential, I don't think it's right. Oskar didn't pay his workers, he payed the SS certain amounts of money for different kinds of workers. Polish people were worth more than Jewish woman, for example, which is why he used Jewish people; they were cheaper. I do agree with the fact that he allowed them safety for the work that they did, which is basically a payment of life. Obviously the time period is the 1940's, and Oskar does not fit in with society, because Germans were not "fond" of Jews at the time, and Oskar was harboring them in his factory.
One big decision Oskar had to make was whether he was going to convert Emalia; his factory, into a Plazow sub-camp or not. Plazow was being converted into a concentration camp, and after the Krakow ghetto was liquidated, the Jews were all being taken from Krakow to Plazow to die, and some of Oskar's workers were those Jews. He wanted to get permanent residence of them in his proposed sub-camp of Plazow, where they would be safe. He got Amon Goeth, who was a powerful person during WWII, on his side to build it, and it ultimately happened. I am glad he did this and support it fully, because it saved hundreds of lives. This was probably where a majority of his 1100 saved lives came from.
