"Anyone who is concerned about working Americans — the people who are at the bottom and the middle — would have to conclude that tax policy has not been geared to help them, particularly in the Bush years and the Trump years,"  Steve Wamhoff, one of the study's authors, told The Hill.

“任何关心工作的美国人，也就是处于底层和中层中的人们，都将得出这样的结论：税收政策并没有帮助他们，特别是在布什年和特朗普时代，”研究报告的作者之一，史蒂夫·瓦姆霍夫，告诉国会山庄报。

ITEP found that from 2001 through 2018, the tax changes have reduced federal revenue by $5.1 trillion, and by the end of 2025, they will have reduced federal revenue by $10.6 trillion.

2012年，当布什减税和奥巴马减税政策生效时，最高收入者看到2000年后税收变动占其收入的最大份额。

In 2015, when some of the Bush tax cuts were reversed for high earners and the ObamaCare taxes went into effect, groups across the income spectrum received similar-sized tax cuts from the post-2000 tax changes as a percent of income.

2015年，当布什对高收入者减税以及奥巴马医保税开始生效时，所有收入阶层都受到了类似规模的税收削减，从2000年后的税收变化占收入的百分比。
