Unfortunately, this liberal idea of fairness has very little to do with actual justice. It often proposes in justice. Liberals oppose actual social justice, while loudly advocating it.
All justice is social.
It takes at least two people to assure justice, because justice involves how people treat each other. Justice, in fact, means giving people their due . If I promise a grocery store two dollars for a gallon of milk, I treat the owners justly if I pay it. The owners deserve to get the price for their property that I have consented to pay. If I take the milk and do not pay the price, I have not only stolen.
