The United States relies on generous tax incentives to encourage personal retirement savings, but these incentives are poorly targeted and yield limited returns. More than 80% of the value of these incentives goes to the top 20% of taxpayers, who earn more than $100,000 a year.
美国依赖慷慨的税收激励鼓励个人退休储蓄，但这些激励定位不当，成效有限。这些激励的价值有超过80%落在了最顶端的20%纳税人手里，他们的年收入超过100 000美元。此外，尽管这些激励每年给美国财政带来1 000亿美元的成本，却几乎不能刺激新储蓄；相反，它们导致高收入纳税人把储蓄转移到具税收优势的资产——这正是总统奥巴马计划给退休储蓄税收优惠设定上限的原因。
