In theories of justice, what is meant by “equality of opportunity” and “equality of resources”, “equality of outcomes”. Briefly explain each concept, citing a few of original authors supporting them. What is the role of responsibility in these theories of justice?
Suppose you are the social planner. Consider the below situations and determine what should be done in each case? While your answer is subjective, you will get points if you support your arguments with different theories of distributive justice concepts mentioned in the document above and explain your reasoning logically:
a) Person A is born with high IQ and talent whereas person B is not. The amount of effort they exert in their work is the same but due to productivity differences, person A earns more. Should there be a redistribution of resources so that person B is compensated for his lack of high skill?
b) Consider again person A has high skill and person B suffers a particular disability that leads to low productivity. Does your answer to part a change? Should there be a redistribution of resources so that person B is compensated?
c) Suppose two people have same skills and exert same effort in their jobs. However, person A was born in an advantaged family and accessed quality education, whereas person B lacked this advantage. Person A made connections in school years with other children from advantaged backgrounds and this helped person A to get good job opportunities such as managerial roles. Hence, person A earns more than B due to opportunity differences. Should there be any redistribution in this case?
