Basically MMT is about the fiat monetary mechanics of government debt and Wisdomics-Gracenomics is about the much larger reality of personal and private commercial debt. MMT is monetary macro-economics and Wisdomics-Gracenomics is the integration of both micro and macro-economics. MMT is a good and important step in the direction of the new paradigm and Wisdomics-Gracenomics IS the new paradigm.
Similarly, Public Banking is a necessary and significant reform, and a publicly administered national bank and central bank are an integral part of the new paradigm of Wisdomics-Gracenomics.
MMT and Public Banking are parts of the whole of Wisdomics-Gracenomics.
