Apart from questions of fairness, cutting top tax rates is an inferior way to increase spending, because the rich have a higher propensity to save. Tax reductions should be targeted specifically at the poor if one wants the money to be spent to stimulate the economy.
抛开公平问题不谈，削减最高税率也是劣于增加支出的办法，因为富人的储蓄倾向更高。减税应该明确地针对穷人，如果想让人们把减掉的税收花出去从而刺激经济的话。
