Wisdom is all relevant data and every possible relevant situation integrated in the most optimally ethical fashion. Therefore, by definition, it cannot NOT include….all relevant realities…often including those realities that others will not consider…because the consideration of them being “unrealistic” actually blocks their entry into their minds. Couple that reality with the sociological fact that research has shown that when only about 10% of the general populace begins to believe something new is true its nearly impossible to stop it from becoming generally perceived as such and a few million man marches plus a focused and determined insistence upon very concrete and imminently doable policy mandates and you’ve got a mass social movement that herds the entirety of the political apparatus toward an actual solution.
Wisdom does not lack data. Wisdom does not lack study or awareness of the various fragmented bodies of thought humanity calls its “sciences” both hard and soft. What economists and the world lacks is a sufficient awareness of the power of Wisdom which by the definition above must also include the integration of human consciousness of itself and of ethics. And when you also begin to see how the highest concepts and experiences of the world’s major Wisdom traditions perfectly align with the stated goals of economics (amongst other studies), and can also align its policies with such philosophy/Wisdom so that they effect precisely what is intended…that is when economic fear or despair or cynicism becomes confidence.
