Agreed. So in saying... ...we are saying that Economics, although having basic laws and properties, similar to physics, math, or medicine, exists in different dynamic than those other fields of study? In economics, unlike, physics, math, and medicine, when we attempt to modify our responses to the basic laws and properties, we can clearly see the results, whereas in economics we can argue 'til the cows come home over free trade vs. protectionist trade policies. In physics, two guys in an airplane argue over air resistance and Newton's description of gravity. One argues that his parachute will counter the force of gravity enough for a safe descent, the second one argues that he can flap his arms fast enough like the birds he's seen. They both jump. Argument solved. Physics will not bend to self-interest. Does this sound correct, or am I just being hopeful out of self-interest? :)Economics is haunted by more fallacies than any other study known to man. This is no accident. The inherent difficulties of the subject would be great enough in any case, but they are multiplied a thousandfold by a factor that is insignificant in, say, physics, mathematics, or medicine—the special pleading of selfish interests. While every group has certain economic interests identical with those of all groups, every group has also, as we shall see, interests antagonistic to those of all other groups.
