The author operates from the assumption that keeping rates low is stimulative. While true in many and most circustamnces, the Fed took rates to zero on an emergency basis in the 2007-2009 crisis. While originally stimulative over time the evidence that zero rates are providing stimulus is weak in fact it's likely that the harm it does to pensioners, savers and others dependent on the debt markets is not only anti stimulative- it may set us up for a new crisis. In short, the piece is done by someone with no econoic training and super prone to grandstanding and the piece feels exactly like that.
