Well for whom? Another aspect of this problem is an economic solution can have winners and losers. An economic policy that invokes slavery as solution to labor issues may actually be 'logical' but clearly puts the interests of one group over another. Economics is just the science resource allocation after all. People have some serious biases when it comes to deciding policy on who gets what and how.

Economics both describe and prescribe, so those models should be evaluated on their predictive power and on whether they have actually done any good.
