Wealth taxation of individuals and equity: A political-cultural market theory perspective

Abstract

Although wealth inequality is increasingly considered a massive societal problem, only a few jurisdictions charge wealth taxes on a wide range of assets on annual due days.

Against this backdrop, the present paper asks whether there are reasons to tax wealth from a tax equity perspective. It interprets tax equity as a procedural rule, which means taxing people with equal ability to pay equally and people with unequal ability to pay unequally. Since ability to pay refers to ‘economic capacity’, which is often understood as economic power, which in turn depends on the interpretation of market theories, answering the research question requires reference to market theories.

The paper shows, firstly, that economists who argue that a wealth tax in addition to an income tax leads to double taxation refer to neoclassical market theory and its power interpretation. However, neoclassical market theory is not adequate to justify that wealth should not be taxed.

Secondly, the paper provides an alternative ability to pay interpretation and a different understanding of wealth. It refers to political-cultural market theory that explicitly deals with power and power distribution. From this perspective, there are reasons to ascribe an ability to pay to wealth that is independent of the ability to pay of income. For that reason, taxing individuals’ wealth supports tax equity.

Thirdly, the present paper asks whether wealth taxation is feasible. It finds that, from the perspective of the political-cultural market theory, the main obstacle preventing the introduction of wealth taxation lies in the prevailing neoclassical market culture.
