He's right. As has been pointed out, that all falls apart when you stop irrationally pretending deficits don't matter. (Deficits being what we're actually talking about) Consider the trillions we've paid in debt and interest to cover insane Republican tax cuts. The trillions our descendants will keep on paying. In actual effect, a tax cut without a prior and proportional spending cut is just another way to blow money, regardless of what Arthur Laffer thought. Republicans have been on the "deficits don't matter" train for my entire life. Republican Jesus got that ball rolling, and I guess they've decided it would be blasphemy to stop and think about it for 5 minutes.
We've had this exact discussion so many times on OGPCF. Republicans have been driving batshit deficits since Reagan, and they've convinced the ignorati that it's a good idea. (Actually, now that we've got the complete Obama administration [and the costs of the 2008 crash and Great Recession] behind us, might be interesting to see if Democratic administrations have caught up...oh wait, we're going by Congress. So, really, Obama is completely off the hook, it would seem...all those crazy deficits to keep the economy from collapsing completely, well, Republicans get to eat that, too. Which is only fair, considering.)
Basically, Galt, your argument hinges on my unfortunate literalism when I said "spending"...but for the covered reasons, it's nowhere near that simple. But you know all this already.
Apologies. I shouldn't have been so precise. I should have said "blow money" or "insane deficits" or "catastrophic debt growth" or something.
