向上流动的前景是否会削弱对再分配的支持?

Does the prospect of upward mobility undermine support for redistribution?
Journal of Public Economics · 2025 · Don A. Moore、Rene Choudhari、Aileen Wu

中文摘要

尽管美国存在严重的经济不平等,许多本可从再分配经济政策中受益的美国人却投票反对这些政策。这种反对或许可以用其对向上流动前景的夸大信念来解释。也就是说,人们可能反对对最高收入和大额遗产征收更高的税,因为他们高估了自己未来适用这些税收的可能性。本研究采用实验方法考察美国人对自身未来富裕程度的信念,并分析这些信念与其对再分配支持程度之间的相关性。研究结果并不支持这样一种理论,即对未来富裕程度的过度自信削弱了美国人对再分配的支持。相反,人们所表达的意识形态立场容忍经济不平等并反对再分配,且基本不受其个人经济利益的影响。

Abstract

Despite substantial economic inequality in the United States, many Americans who would benefit from redistributive economic policies vote against them. This opposition could be justified by an exaggerated belief in the prospects of upward mobility. That is, people may oppose higher taxes on the largest incomes and estates because they overestimate the degree to which they would be subject to them. This research employs an experimental approach to studying Americans’ beliefs about their own prosperity and correlates these beliefs with support for redistribution. The results are not consistent with the theory that overconfidence about future prosperity impairs Americans’ support for redistribution. Instead, people report ideological stances tolerant of economic inequality and opposing redistribution, largely independent of their private economic interests.
