There can be no one best method or morphology of social and governmental organisation. Some forms are certainly better than others when measured on a metric of utilitarianism or social and international harmony. Progressive refinements and approximations towards more efficient, effective and equitable forms of social system is the only plausible or realisable goal. Limited psychological attachments to a reflexively self-defining narrative of complete and final organisational closure and systemic completion is the primary source of failure, conflict and long-term economic and political (or ideological) turbulence.
Is this self-evident? You would not think so from the proliferating crayon scribbles and simplistic slogans of nationalist and ideological fervour being flung like wet mud across the contemporary international political and geo-strategic stage.
