You are entitled to your opinion, of course, but unfortunately this process is how our understanding of the world has increased so rapidly over the past several hundred years - laboriously proposing new models, often from intuitions we have derived from observations, and then trying to test those models by obtaining experimental evidence. If things bear out then we put more effort in, and conduct more thorough research. There are many instances of poor practice within that framework, but the process _as a whole_ has worked pretty well so far, and what is discussed here is pretty standard. As for the Nautilus post itself, it is just an interview with someone who works in the field, not a rigorous scientific document, and they are free (surely?) to express their views about whatever they and the interviewer wish to discuss. To your later points - I don't know what "understanding the private sector" or "understanding the economy" mean to you, but I would suggest that the person in question does have _some_ understanding of the economy (at least), inasmuch as they have contributed to a formalised understanding of the dynamics of the economy as we (humanity) currently understand them. I'm not entirely sure what else you want - perfect predictions or go home? Frankly it just sounds like you disagreed with what they said, but, as I already mentioned, you are as entitled to your opinion (as they are to theirs).
