In Canada Martin you have the opportunity to read and understand ALL of
what Keynes had to say. Guelph is the institution that eventually brought
all of his writings together.
Whilst you are right to say he was involved in orthodox economics, with
all its unsatisfactory aspects, he also wrote, and believed many things
that he was never able to get beyond the gatekeepers.
For instance he said that the money that he wished to see put into
circulation should be at zero, or near zero interest. He went further. He
called for the "Euthanasia of the Rentiers".
But in accepting the correctness of Douglas analysis he didn't need to be
so snobbish, did he?
Then that was Keynes for you :-))
