Social: "of or relating to human society, the interaction of the individual and the group, the welfare of human beings as members of society; tending to form cooperative and interdependent relationships with each other." Merriam-Webster
Social Justice: "justice in terms of the distribution of wealth, opportunities and privileges within a society." English-Oxford Living Dictionaries
At the core of social justice is providing equal representation and economic opportunity to all citizens. Corporations are not people or citizens, they are structures created and regulated by a Democracy by which people pursue wealth, improvement and progress. Corporations do not have a "life" outside of that given to them or taken away by THE PEOPLE.
"I'll not accept corporations are "persons" until Texas executes one of them."
