What was everyday life like in auschwitz in terms of clothing, food, and the bathrooms?

It depends basically on how long they can survive if they lost their job: if loosing your job means you are facing eviction if you don't find a job in six weeks then you are working class. If loosing a job means that you might need to sell your car if you don't find a job by next year then you are middle class.

Hope it helps mate:)
