经济分析表明, 20 世纪中叶的繁荣源自工会和福利, 而不是高税. Economic analysis suggests mid-century prosperity stemmed from unions and benefits, not high taxes.

最近的一项分析表明,虽然20世纪中叶的中产阶级在高税率时期最强大,但当时的繁荣更多是由工会,广泛的福利和利益相关者资本主义推动而不是税收本身. A recent analysis suggests that while the mid-20th-century middle class was strongest during high tax rates, the era's prosperity was driven more by labor unions, widespread benefits, and stakeholder capitalism than the taxes themselves. 随着时间的推移,放松管制,全球化和有利于股东价值的政策削弱了劳动力,导致生产率与工资之间的差距越来越大,中产阶级也在缩小. Over time, deregulation, globalization, and policies favoring shareholder value eroded labor power, leading to a growing gap between productivity and worker pay and a shrinking middle class.
