Reducing individual tax rates and taxes on savings and investment at best fosters modest increases in employment, work effort, and income. Despite the Bush-era tax cuts, the 2001-2007 expansion was the worst of the post-war period in terms of investment, employment, wage, and GDP growth.
罗姆尼对其税收计划的长期增长效应也有所高估。降低个人税率和储蓄和投资方面的税负充其量只能使就业、工作投入度和收入略有增长。尽管布什时期实行了减税计划，但从投资、就业、工资和GDP增长看，2001—2007年的经济扩张仍是战后以来最低的。就业创造和经济增长在克林顿总统20世纪90年代的增税政策实施后要比布什时期强劲得多。
