The balanced budget is to the economy as never using the accelerator is to a car. Using the accelerator too much is dangerous, not using it when there is freight train bearing down on you is also dangerous.
Well, we’re not at any risk of not using the accelerator. :-)
And we’re still stuck at long term growth levels which are insufficient to maintain living standards, so that’s a bit of a problem. Hopefully, this recent 3.0+ level will continue, but one datapoint does not a trend make.
