Distributive justice makes sense in a legal system, but is terrible social policy. We can probably agree that everyone deserves a right to a fair trial and that we should be able to rely on a police force to keep us safe, but what about when it comes to how much everyone has?
Should one person go to work every day and be taxed so that he or she can help support those who do not work? It seems we used to allow for that when people were off work for temporary reasons, but finding ways to live off the system has become a way of life for some people.
What is fair about that? If taken to the logical extreme, we would see society break down as those who go to work to support those who don't would eventually start staying home and living off the system, too.
