It doesn't really matter what the academic plan is, the policy isn't going to follow it. Much like how interest rates were supposed to rise after being dropped to emergency levels a decade or so ago and instead a 25 bps rise is front page news.
All the politicians/relevant voters are looking for is a green light to hand out money and some buzz to say that it'll make everyone better so ignore the doubters. If they cared about good economic policy the last few decades would look very different. The dominant ideology is that centrally planned interest rates are a good idea, and that is questionable.
