The effect of the caste system is to create a society that has little social mobility.
Social mobility is the movement of individuals, families, or people of certain categories within a social strata in a society. Social mobility allows the social status of people to change relative to the social status of other people within the society.
Caste system limits or prohibits social mobility. You are already part of a caste even before you are born. Your caste is based on the caste of your parents and you are part of said caste until the day you die.
