It does not "indicate" any such thing.
With the economic hits of high oil prices and climbing interest rates, there may very well have been job LOSES and recession if the tax cuts had not kept money in buyer's pockets.
That's the key all right. But in whose pockets? Counter-cyclical tax cuts and government spending increases are standard Keynesian economics. But these are supposed to be middle-class tax cuts which stimulate private spending. Large tax cuts for wealthy individuals were supposed to stimulate business investment (and job creation). The authors argue that they didn't.
