"I seriously doubt that people like Robert Reich, Paul Krugman, ... etc. are too concerned about short-term fluctuations in the stock market." Of course not. They are mostly "concerned" with partisan politics and the future of the Democratic party. You can give them the title "economist" (the flimsiest of all professional titles anyway, whether worn by Arthur Laffer, Robert Reich, or even Milton Friedman, for that matter) and hang all the awards you want on them, but they will, somehow, always just happen to find that whatever economic nostrum is being peddled on the left side of the aisle--whether or not that nostrum is in tune with liberal thinking in general--is the proper remedy for whatever ails us. The only exception is when they decide to feign disagreement over the dosing of that nostrum in order to separate themselves from more conservatively oriented economists with whom they don't wish to agree.
They (like conservative economists) will also predict the course of past recessions, and any past part of a current recession, with incredible accuracy and detail.
Are these things really not patently obvious to everyone?
