"consensus means nothing but politics"
Actually, why don't you do this if you think it's all about politics. Get your favorite politician, see who their economic advisers are, then understand their views. Mankiw stated economic points that are accepted by a wide political spectrum.
Until such model exists, consensus means nothing but politics. Maybe, just maybe, we should start considering demote economics status to "pseudo-science." Last time I check, fortune tellers also agree on shit, you know.
