Can you compare and contrast the caste system with a class system?

The Indian Caste System, or varna, of India came about when the Aryans began speaking nomadic groups came to India about 1500 BC. The Aryans priests divided society into a caste system with four parts. The first varna were priests, the second was rulers and warriors, third in rank was farmers, craftspeople and traders. And the lowest rank was workers and servants. People couldn't change their caste and they had to marry and socialize with people from their own caste.

In the united states class is determined by how much wealth you have, not usually by your occupation. The 3 classes are upper, middle and lower class. Most Americans fall into middle or lower class with the very people in the upper class. In American society, you aren't forced into one class. Our system is not based on religion like the caste system is.
