MAUS: What does Vladek’s experiences illustrate about the possibility for individual choices and actions during the Holocaust?

In Chapter Four, we learn that Vladek's father and Anja's grandparents are all sent to Auschwitz. At the same time, Vladek is beginning to show the resourcefulness and thrift that will help to see him safely through the war. While the rest of Anja's family is living off of their savings, Vladek immediately begins to generate income by selling cloth on the black market. He gives half of his money to Anja's family, but always keeps half for himself. He is also extremely adept at thinking on his feet, a trait that saves him on more than one occasion.
