In standard analyses, the tax cut brings a reduction in government purchases of goods and services, like defense. But a tax cut could instead contract the welfare state – social assistance and social insurance, which constitute social wealth.
然而，我们必须步步为营。根据标准分析，减税会使政府削减财务和劳务购买，比如国防开支。但是，减税也会减少福利承诺——社会援助、社会保险，此两者是社会财富的组成部分。从那个方面来说，减税虽然逐渐增加了个人财富，却会降低社会财富的数量。这是一个实验性的问题。
