All of the Post Keynesians and MMT theorists have the same problem as apologists for the Church had during the Reformation. They miss/resist/are only partially aware of the necessity of directness in policy/problem resolution. In other words if the economic system itself is now inherently cost inflationary then injecting money as Debt/Loan into the economy instead of directly to the individual first and also directly at the end points in the economy to enterprise….will merely re-initiate the cost inflationary nature of the system. Directness is an essential concept to be strategically applied in the economy.
Study paradigm changes and you will see that directness and other aspects of the philosophical concept of Grace and/or consciousness itself are always the essential factors in the resolution of the old problematic paradigm and the change to the new one.
