That most of the mainstream media do not forcefully refute the misinformation that these guy spew on TV and radio is one of the reasons that Americans remain ignorant to our fiscal realities because they genuinely believe the information they are hearing is basically accurate or at least debatable.
The reality: Tax cuts do not reduce deficits or generate increase economic activity. It is the Keynesian effect that gives the semblance of tax cuts increasing economic activity, given that inasmuch as we cut taxes, spending is not curtailed to offset the tax cuts and as such, generated a stimulus (deficit spending).
The Rachel Maddow piece below on tax cuts and Republican Party talking points is informative.It would be funny if it did not have such a material impact on all of our lives.
