Tax cuts given mostly to the rich— like the current Senate Plan— will not grow the economy and tax revenue enough to pay down the deficit. The simplest reason why is that the small group that makes up the richest Americans already spends and invests in large amounts and therefore, by adding more tax breaks— even large cuts— we will not generate high rates and amounts of middle class spending growth which would be generated by a middle class tax cut. In addition, the higher the cuts to the top brackets, the lower the amounts to flow downward and generate the rate of increase of middle class spending that directly and rapidly increases the rate of economic growth— millions of middle class Americans buying things drives rapid and immediate production of goods and services, then investment and job growth, and  the tax revenue increases that pay down the deficit.
