During the long period when human beings were evolving before the development of civilization, they lived in groups of related families and small tribes. Tribalism probably played a positive role in their survival.
Since the development of civilization, however, tribalism and the human adherence to similar but larger groups have, all things considered, probably been a bane. Certainly the nationalism and imperialism of the past several centuries have been.
In a world where the technology allows far-flung interactions -- economic, cultural, scientific, and personal -- among individual human beings, collectivism lies at the root of destructive institutions, including the pervasive Big Government plaguing the world today.
In ideology, collectivism sails under various banners -- communism, socialism, fascism, nationalism, progressivism. In economic analysis, collectivism is known as macroeconomics.
In ideology, the world desperately needs the abandonment of collectivism and the embrace of individualism in every realm; the substitution of market relationships for the menacing commands and threats of governments at every level.
In economics, the practitioners need the abandonment of macroeconomics, with its inevitable sequel of coercive attempts to manage, direct, and shape overall economic activity, and a return to the search for a better understanding of individual human action.
The combination of tribalism, especially nationalism, with modern military technology threatens the survival of the human species and the destruction of the magnificent, now-global network of commercial, cultural, and scientific cooperation people have built through the centuries. The world needs a revival or, where it never took root before, the establishment of individualism in ethics, ideology, and economic analysis. Adelante, amigos.
