Economist: Although obviously cuts in personal income tax rates for the upper income brackets disproportionately benefit the wealthy, across-the-board cuts for all brackets tend to have a similar effect. Personal income tax rates are progressive (i.e., graduated), and if total revenue remains constant, then across-the-board cuts in these taxes require increasing the interest rates. This favors those who have money to lend, once again benefiting primarily the wealthy.
