And so, from 1970 to 2000, a broad coalition of conservatives (who wanted to see the government stop encouraging immorality), centrists (who wanted government money spent effectively), and leftists (who wanted poverty alleviated) removed the “notches” from the social-insurance system. Presidents Jimmy Carter, Ronald Reagan, George H. W. Bush, Bill Clinton, and even George W. Bush and their supporters created the current system, in which tax rates and eligibility thresholds are not punitive disincentives to enterprise.
1970—2000年，保守派（他们想让政府停止鼓励伤风败俗行为）、中间派（他们想让政府把钱花在刀刃上）和左派（他们想减贫）组成了广泛同盟，把“等级”从社会保险体系中逐出。卡特、里根、老布什、克林顿甚至小布什诸位总统及其支持者创建了当前的体系，税率和起税点不再起到抑制企业的反激励效果。
