Why do Tories like the NIT while Labour calls for a UBI?
In my previous blog, which you can find here, I investigated the economic rationale behind a Negative Income Tax (NIT) and a Universal Basic Income (UBI), arguing that the former exhibits greater effectiveness in combating poverty but might discourage individuals to work, while the latter incentives greater participation of low-income individuals in the labour market at the cost of a lower effectiveness in tackling poverty.
However, this economic assessment is not the only lens through which these two policies can be analysed and usually fails to explain why right-wing parties tend to support a NIT while left-wing ones prefer an UBI. This political divide is mainly to be connected to the ethical – rather than the economic- differences of the two policies, with a NIT relying on a libertarian view of freedom and equality while the UBI arising from an egalitarian one.
The first key aspect that distinguishes the ethical foundations of NIT and UBI relates to their perspectives on freedom. Examining freedom from a negative standpoint involves considering an individual free when they can carry out their actions without interference from others or groups (i.e., they are free from). Emphasising the concept of negative freedom is intrinsic to libertarian thinking, as it necessitates the establishment of minimal legal frameworks and a governing authority to safeguard individuals' self-determination.
In contrast, from an egalitarian standpoint, an individual is deemed unfree if they lack the means necessary to pursue a goal and be autonomous, even if no other individual or institution obstructs their path. Positive freedoms can therefore be described as opportunities (i.e., they are free to), and their maximisation necessitates redistributive measures, which are ensured by a stronger and more active state.
A second factor is individuals’ approach to uncertainty. On one hand, the libertarian stance acknowledges that different individuals possess varying degrees of risk aversion when engaging in economic activities. This implies that individuals make choices regarding their employment status, investments, and consumption based on their unique risk preferences. In this view, the market system ensures equality of treatment among individuals.
On the other hand, the egalitarian viewpoint perceives and justifies redistribution as a response to the widespread risk aversion exhibited by all individuals. This argument is rooted in the notion that, given individuals' lack of knowledge beyond moral considerations (referred to as the veil of ignorance), they would collectively support the existence of institutions dedicated to redistributing the products and benefits stemming from the arbitrary distribution of abilities and talents.
Based on a libertarian view, a negative perception of freedom and a probabilistic approach to uncertainty would reject any form of equality beyond equal rights, thus opposing any form of compulsory fiscal imposition. However, assuming the necessity for the existence of such a policy, state intervention should be limited to preserving the essential tenets of libertarianism.
Therefore, any public redistributive scheme should exclude any form of needs, the link with the market should be as weak as possible and the role of the state should be as less invasive as possible. In this context, a NIT scheme is often argued to be a redistributive policy that adheres to these constraints by implementing exemptions and deductions from taxable income and only taxing the portion that exceeds a certain threshold. On the other hand, a positive perception of freedom, which asserts that true freedom encompasses both the means and the rights to pursue one's desires, along with a risk-averse approach to uncertainty, leads to a policy that addresses people's needs with an unconditional requirement. This is exemplified by a UBI, which aims to meet individuals' purchasing power without imposing specific conditions.
