I think that the point is that "economist says" should be the beginning of a debate, not the end - it's a data point, but not conclusive evidence in favor of or against whatever's being referenced in most situations

What other inputs into the decision should be included? I'm kind of at a loss as to what other approaches would complement an economic one, even acknowledging the severe limitations of the discipline.
