The Caste System
The term "caste" is used to describe stratified societies based on hereditary groups not only in South Asia but throughout the world. Others might present a biological explanation of India's stratification system, based on the notion that all living things inherit a particular set of qualities.
At first the German government encouraged Jews to emigrate and placed a few restrictions on what they could take. Gradually, the Nazis sought to deprive Jews fleeing Germany of their property by levying an increasing heavy emigration tax and by restricting the amount of money that could be transferred aboard the German banks.
Hope this helped :)
