It is hard to imagine that so little progress has been made in dismantling the mainstream macroeconomics paradigm over the last decade within the institutions of government. We have had the GFC, and now, the pandemic to disclose what does and does not happen when governments engage in relatively large fiscal shifts, yet the fictional world that is taught in mainstream university programs and echoed in policy making circles keeps being rehearsed. While researching the literature on rates of return on public infrastructure spending for a project (book chapter) I am working on at present, I came across the starkness of the mainstream deception. They are still claiming that public spending damages private spending.
