Answer:
Members of a high caste enjoy more wealth and opportunities while members of a low caste perform menial jobs. The highest class/caste is the Brahmin, and the lowest, are the Untouchables, or pariahs. To be born into an Untouchable caste meant you were looked down upon society, and people, like the name Untouchable, could not even touch you. People in the highest caste had more job opportunities, and had more privileges.
Hope this helps!
