Cabaret: What's going on in Berlin?

When watching a portion of the film Cabaret, I noticed several important features that reflect everyday life in Berlin before WWII. A great amount are mainly expressed through the cabaret itself, a lot of the times symbolically. Right off the bat, there is an image of a crippled Nazi strolling down the street at one point. This image can be considered an oxymoron - as Nazis promise stability and security to their supporters, some are still crippled from war, physically and mentally. As the main characters walk down the street, we see dozens of torn up propaganda posters for parties other than the Nazi party, showing that things are shaking up in Berlin and change is bound to come. Nazis entered the cabaret asking for donations for the Nazi party. At the same time, a "boxing match" act was being acted out on stage, perhaps representing the actual violence (or violent ambitions) behind the Nazi's presence. Surprisingly enough, we witness Nazis beating up the man who kicked them out of the cabaret, which cements our understanding of Nazi methodology: teach a lesson to whomever stand in the way. Money and economic crisis is also a topic of the film. The main character who works at the cabaret says, "Everyone's broke, but who isn't?" This statement tells a lot about life in Berlin and how people are struggling to find work and money. She ends up performing a song at the cabaret about how "money makes the world go around," clearly symbolizing the struggles in Berlin at the time. The cabaret acts as a very important (and accurate) source for the conditions in Berlin. The songs exaggerate the struggles to show just how severe life in Berlin is. These obvious flaws in German life at the time opened doors for the Nazi party to take control and execute their ideas on the german population.
