The tax cut is like sugar at a birthday party. It will cause a short term boom, but soon enough that stimulant will be adjusted for, and when the recession comes, the government will have less flexibility to use fiscal stimulus to restart growth. Furthermore, to finance that tax cut, a lot of money is being borrowed. When government is out there shilling its bonds, this crowds out investment into corporate bonds and equity, depressing growth.
