That is an odd read. It sounds as though he thinks he is talking to an idiot, which perhaps he is, with the “stuff” and all.
And tax rates and policy is “fiscal” policy.
I believe he is cognizant of the reporters liberal views. He took “fiscal policy” to mean spending which is probably what the reporter meant anyway.
I am interested in his study of relationship between tax cuts and economic growth. We KNOW that there is a direct cause and affect and we know why. But, it has never really been fully measured...pretty complicated task.
