Stephen Darling points me to this blog post by Bill Mitchell, Wray's co-author [but not of the book I am reading], responding to Marxist critics of MMT. I found it extremely interesting. Three quick thoughts: One, Mitchell gets Marx right; Two, this is deeper into the weeds than I want to go; Three, it looks to me as though Marxists and MMT defenders ought to be natural allies, not opponents. They both criticize mainstream economists for the same fundamental failing.
United Front, anyone?
