well i seemingly have a very different viewpoint, because the most interesting economics bits are econometrics, essentially data science - the same things all other stem folks use to find the underlying distribution, estimators, their significance, finding the p value. Using this to model whole world is just as wrong as saying all of chem is solved by taking mendelev periodic table. sourely it works, and explains some stuff, but just knowing it does not predict all of chemistry. same way, for example ls-lm model (suppply demand curve) does not explain the whole world, and good economists do not claim they can explain it (sorry for using bad examples, 1 only took 2-3 eco courses).
