You have a point, but unfortunately, the only discipline which claims any real insights into fixing the economy is economics. You know, the "dismal science." It is the discipline in which the introductory books outline the basic rules. Supply, demand, production possibilities curves, all that sensible, good stuff. It all makes sense --- experts in economics should be able to wisely guide nations and markets, right? Then, the intermediate-level books and classes teach you that some of that intro-level supply-demand stuff is pretty wrong. It only operates under all sorts of unrealistic conditions, kind of like equations in high school physics which disregard friction. So intermediate econ outline all sorts of complications which supposedly help in the real world. Then, in the seminar-level classes, you learn that none of the intermediate-level theories really ever worked except by accident, and no one who tries to predict or model real-world economic conditions agrees on anything.
