The problem with rejecting economics' claim to be a science on the basis its underlying assumptions survive even as models based on them are usually out by a few percentage points (and under certain circumstances give counterintuitive results) is that you'd probably have to throw a lot of natural science with the bathwater. Physics is the exception rather than the rule for the accuracy and robustness of falsifiable predictionswhilst medics - like economists - are left with statistical tests, ad hoc explanations of confounding factors and a raft of exceptions that arguably falsify claims as uncontroversial as "drinking in excess is bad for your health". On the other hand, unlike astrology or homeopathy neither discipline is afraid of testing its assertions against a null hypothesis.
