There were two particularly important reasons why the state might have sponsored such organized ridicule and abuse of minorities. The first reason was that identifying minorities in this way allowed people to have someone to "blame" for the problems of the country. Minorities were accused of causing financial problems, or hoarding jobs or of accumulating wealth they did not deserve.
The second reason why this attitude was useful to the state was that it encouraged the unity of people who did fit the traditional definition of "German." By having a common enemy, white Germans were more likely to become unified and to collaborate with one another in the development of the Nazi state.
