As someone who studied diligently to obtain his M.A. in Economics and who also taught Principles of Microeconomics, Principles of Macroeconomics, and Intermediate Microeconomics in a state university and also a graduate MBA course in economics at a Catholic university, this quote from the article rings true:

(Actually, as a lawyer, I can make the same observation about American law--there is much less intellectual weight there than meets the eye, regardless of our august courtrooms and robed functionaries.)
