The problem with models in economy...

... is that they are soon considered as dogma, while they should only be the starting point of a discussion. There is some indisputable truth about Malthus's idea that a population growth following geometric progression and a growth of food production following arithmetic progression can only lead to a disaster. The problem starts when one tries to turn it into a prediction, extrapolating from the model to the real world and mostly ignoring all other forces existing in reality but not present in the model. It should be obvious that economy is too complex to fit in any model. Yet all major schools of economy from the 19th and 20th century seem to have fallen into the hubris of believing they could use their models to predict the future and shape the present. With disastrous consequences when their ideas came to power. Dogmatic marxism and neoliberalism have left millions suffering. But the gloss of scientific respectability economists provide appeals too strongly to any ambitious politician for them not to abusively use it to cover their questionable politics as a necessity. "There is no alternative", we are told each time. And media rely the propaganda until people start believing dogma are obvious truths and consider anyone challenging it as a delusional lunatic.
