To be honest, the person in the Whitehouse has very little to do with the economy. Laws are made by congress and the effects of those laws usually aren’t evident untill years after they go into effect.
However, the corporate tax cuts have definitely boosted the economy and drove down unemployment since businesses have less incentive to move operations overseas taking jobs with them. They are also investing and growing their businesses more now that they have less tax obligations. And with more jobs, there are less people needing government assistance and are paying more income taxes, now that they actually have income.
