This is the final part of my three-part series on the why I have confidence in the primacy of fiscal policy over monetary policy and eschew any proposals, by other Modern Monetary Theory (MMT) advocates or others, to replace the so-called ‘independent’ central bank, with an ‘independent’ fiscal authority, which they seem to think would take the ‘politics’ out of fiscal policy decision-making and focus it on advancing the well-being of the people. Such a proposal is not core MMT. It is an opinion that, in my view, is based on deeply flawed logic and would would constitute the continuation of the neoliberal practice of depoliticisation and further increase the democratic deficit that is common in our nations these days. In this final part, I extend the reasons that progressives should oppose such outsourced decision-making and, instead, advocate the introduction of processes that always make our elected politicians fully responsible for the decisions they take on our behalf. Our polity should be always be held accountable for those decisions and not be allowed to defer responsibility to an external source (like an ‘independent’ central bank or fiscal authority).
