Explain how the caste system is structured and why it results in social inequality

The caste system made it impossible for people to move up in social classes, if your father was a plumber you will follow his line of work without chance to escalate in social class.

Explanation:

The caste system primarily used in India as a part of Hinduism never allowed for a person to move up in social class, if you were born into a lucky family (a Politician / Banker) you would take your fathers job, and pass it down to your son and so on. It resulted in social inequality for people because it did'nt allow for a person to move up in social class and get a more profitable/enjoyable job. So in summary if you didint like your job (street cleaner) you cant change it and would have to pass the same bad job to future generations.
