Discuss why unequal access to basic service amount to social injustice, in three points

If a society does not have the economy to provide basic services, such as electricity, food, medicine, water, jobs, housing, clothing, etc. than more people are not going to get the things they need. If they can not get the things that they need through the conventional ways, then many will turn to crime, especially if they are desperate. (I'm sure you can infer from this to fill your question).
