My objection is to the idea that everything true and important can be captured in metrics and quantitatively modeled. Then there is the fact that even to the extent that things like macroeconomics can be modeled (which is never at a level of accuracy that would be accepted in any scientific discipline), it still often fails to capture the social/political dynamics of the moment such that the theory matches felt experience. I believe that economics has largely captured power in social science by essentially stealing scientific authority and falsely claiming it as their own. Then they dismiss other fields of social inquiry as soft and unworthy of equal status even though their own insights are often of lesser value than the supposedly soft social sciences.
