Let’s start with the general - Davidson portrays economists as hopelessly divided and unsure about whether or not debt-financed spending and tax cuts (i.e., something like another Recovery Act, which I’ll just call “fiscal support” from now on) could lower today’s unemployment rate, but relatively united when it comes to how to reform taxes and education and health care systems.
This is the reverse of the truth - there is wide agreement that debt-financed fiscal support in a depressed economy will lower unemployment. Now, it’s true that there are holdouts from this position. And others who think the benefits of lower unemployment are swamped by the downsides of higher public debt (they’re wrong, by the way). But, the agreement* is much more widespread - ask literally any economic forecaster, in the public or private sector, that a casual reader of the Financial Times has heard of if, say, the Recovery Act boosted economic growth. They will all tell you “yes.”
