What does it mean to say that a certain institutional arrangement P in some society S ought (or is morally required) to be? Maybe that comes to this: S is required to come up with and implement a plan to achieve S. And perhaps that, in turn, comes to something like this: each individual and collective agent in society is required to make reasonable efforts, relative to role or position, to promote S (all of us collectively) coming up with and implementing a plan to achieve P. Different agents in different roles would have different more-specific requirements.
Is this kind of analysis standard? What are the alternatives?
If this analysis, or something very much like it, is right, there would seem to be some important results that I don’t think are always acknowledged in discussions of justice with regard to the basic structure of a society.
