How did a person’s caste affect his or her opportunities in life?

Because of human psychology.

Explanation: Many people in this world have discriminatory minds and they do not provide opportunities to that person of low caste and because of the person's behaviour towards him he starts giving up in life. But if a person is of high caste people treat them as their god no matter if he is competent enough or not and because of their behaviour towards him he thinks that he owns the world and looks down upon others.

Members of a high caste enjoy more wealth and opportunities while members of a low caste perform menial jobs.
