When macro-economists like Steve Keen and Michael Hudson explore the correct and most urgently needed area of change, that is money and finance, they can be quite insightful. However, even then they generally miss the true mark and come up with mostly palliative policy suggestions more often than not because the abstract maths and theortics of macro-economics have become so habituated in them that it actually prevents them from looking DIRECTLY at the economic/productive process itself and discerning the points/places in that process that policy can have its best and most paradigm changing effect, that is retail sale and at loan signing.
