Why were the jews an easy target to blame?

They had different belief 's so every one would believe fuhrer

When you want people to pay attention to you you have to give them something to hate. Hitler blamed the Jews for the bad economy etc because Germany was in a bad place economy wise. When he started blaming someone else it was easier to get people to jump on the bandwagon. When he started taking their jobs and shops there was room for others to fill in their spots and because many people of other ethnicities needed jobs they joined the Nazi party. 

Urban growth invariably feeds increased commercialization and industrialization. it requires continually expanding land areas. when urbanization rates are high, and countries do not have the institutional and managerial capacities or economic wherewithal to manage such rapid growths, they exert intense pressure on the types and nature of the resulting settlements. they contribute to the development of overcrowded slums and shanty towns without adequate essential services and necessary infrastructure.-by asit k. biswas and cecilia tortajada
