Anyone who has ever worked in a professional capacity knows that what they are being paid to do is:
1) anticipate problems arising before they happen
2) if they do happen, having a trustworthy set of skills to know how to fix the problem.
One of the professions that does not have to do either of these is mainstream American economists. Then what are they paid to do? Propagandize neoclassical market fundamentalism. Since 1950, 51% of Nobel Prize winners have come from one University, The University of Chicago, spawning ground for market fundamentalism.
