People seem to think that &#x27;zero-sum&#x27; is an analytic shortcut to declaring something good&#x2F;bad. You can&#x27;t actually do this, however neat it seems. You have to consider all the difficult-to-quantify social impacts and intricacies too.<p>Almost every attempt to declare something zero sum will miss out relations, factors, dependencies and links because the model they pick is too simple. Hence the never-ending arguments about trying to define something ZS or not.
