> You cannot just make up an arbitrary model and say this is how we think it works. Perhaps it's meant as hyperbole, but that doesn't happen in economics. Models are not arbitrary, but the result of years of hard work based on generations of research. And then the models are tested and retested against reality. Some problems, such as economics, are important to solve even though the universe does not make it easy for us with an abundance of objective data. 'Why are food prices rising worldwide' is a bit more complicated than 'why does one body fall toward another body of greater mass', but it's just as important.
