"The controversies between the proletariat and the middle class had to be smoothed out and bridged over by each getting to know and understand the other"

In this quote, Fritz Sauckel is highlighting the importance of communication and understanding in fixing conflicts in between the working class (proletariat) and the middle class. He suggests that in order for these debates to be dealt with, both sides must make an effort to be familiar with and comprehend each other. This needs breaking down barriers and stereotypes, and actively listening to each other's perspectives. By doing so, the distinctions between the two classes can be bridged and a sense of unity can be accomplished. Sauckel's words emphasize the need for empathy and mutual respect in creating an unified society.
