ticle you quote says JOHN KENNETH GALBRAITH: Well, Keynes had a couple of conversations with Roosevelt, very famous, and they were deeply unsuccessful. Roosevelt’s system of thought did not extend to a conceptual notion of Keynesian economics. There were other people around Roosevelt, the most notable being Lauchlin Currie… who had read Keynes, and became abreast of Keynes.
Currie had even anticipated him to some extent, but the influence on the master was zero. Let me correct that. The influence was zero, but on the other hand, one of the advantages of zero was that any digit could be inserted. And while he didn’t accept Keynes as a doctrine, he didn’t resist it, either. He had no other system of economic thought [or] economic theory that excluded it.
INTERVIEWER: Would you describe FDR as an instinctive Keynesian?
JOHN KENNETH GALBRAITH: No, I would not describe him as that. I would describe him as an available Keynesian.""
The article you quote from Mostly Economics states that Keynes had little influence on FDR. His ideas were not accepted during the depression. FDR was influenced by Colombia University economists. Tuchill, Mclay ans Adolf A Beale Jr. They were trained in Classical economics the only accept economic theory of the time.
John Kenneth Galbraith, like me , was a Keynesian economists.
