I also like his acknowledgement of what the SF Fed conclusion was wrt the Stimulus...it was necessary to avoid a "Deflation"...determining WHEN to turn the spigot off is always an issue...art, not science...with +/- of 1% in the author's GDP estimate, it doesn't look like it was seriously abused.
I do, however, object to his seeming dismissal of the benefits being provided by the Act...IMO those items are essential investments.
