Like Bill Mitchell's article at The Nation, it is concise, precise, and accessible. However, The Nation is a progressive venue, whereas Forbes occupies the other end of the spectrum. Quite a spread in only a matter of days. Word is getting out on many fronts as editors notice and pick up on the growing momentum.
Prof. Harvey's column is a good one to pass on to MMT skeptics in that he anticipates the common objections voiced by neoliberals and conservatives, as well as progressives with neoliberal tendencies. The piece is well argued, and anyone who is open can readily absorb the policy message, regardless of their persuasion. The comments I saw there are positive, at least so far.
