Economics is voodoo, hopelessly lost in the depravity of reason, in the words of Nietzsche, stemming from confounding of consequence and cause, as I explain here.
Economics is not a science, for it does not challenge its assertions based on contrarian observations of reality, new normalizations of truth or reason. Economics is an art only in the sense that it has artfully enthralled many a hopeless policy-maker, in the same way, any other religion carved from frozen and unverifiable scripture attracts only the hopeless.
