Higher taxes urged to reduce inequality

Introduction

Global wealth inequality has reached crisis levels — the top 1% owns more than the bottom 50% of humanity combined. India mirrors this trend starkly, with one of the sharpest wealth concentration ratios among major economies. Former CEA Kaushik Basu argues that steeper progressive taxation on very high incomes can reduce this inequality without undermining private enterprise — making it a critical intersection of fiscal policy, governance, and democratic health.

Background & Context

The argument for progressive taxation is not new — it has roots in John Rawls' theory of justice and A.C. Pigou's welfare economics. However, the digital economy has added a new urgency: wealth today translates not just into consumption but into ownership of information platforms, giving the ultra-rich disproportionate influence over public discourse and democratic processes.

The UNU-WIDER conference — "Green Industrialization and Inclusive Growth in a Fractured World Order" — brought together economists and multilateral institutions to address how inequality interacts with institutional trust, democratic legitimacy, and sustainable development.


Kaushik Basu's Core Argument

1. Progressive Taxation Without Killing Incentives Basu argues that among the super-rich, wealth accumulation is driven by relative status competition — not consumption needs. A higher marginal tax on income above a threshold would:

  • Leave relative wealth rankings unchanged
  • Preserve competitive incentives
  • Generate revenue for redistribution to poorer sections

"When you become super-rich, you are not trying to earn more in order to buy more cars and mansions. You are just competing with the other super-rich person... If you leave the relative rankings unchanged, the competitive spirit remains exactly the same, but it's happening at a lower level."Kaushik Basu, Former CEA, Government of India

2. Inequality in the Digital Age — A New Threat Unlike earlier eras where wealth translated into physical consumption (mansions, yachts), digital-era wealth buys media platforms and information ecosystems. This has a "silencing effect" on ordinary citizens — concentrating the power to shape public opinion in very few hands.

3. Trust as an Economic Variable Basu highlighted that economic trust — the expectation that parties will honour commitments — is foundational to market transactions. When inequality erodes this trust, it disrupts cooperation, weakens institutions, and reduces economic efficiency.


World Bank Perspective — Luis Felipe López-Calva

The World Bank's Global Director for the Prosperity Vertical identified declining public trust in governments as a symptom of deeper institutional weakness. His framework for restoring trust rests on four pillars of strong states:

PillarDescription
Credible electionsFree, fair, and trusted democratic processes
Political representationInclusive governance reflecting diverse voices
Civic spaceFreedom of expression and civil society participation
Public debateOpen, evidence-based discourse on policy

He called for universal welfare systems over fragmented support programmes, and emphasised that multilateral institutions like the World Bank should provide neutral data rather than shape narratives.


Key Concepts for UPSC

Marginal Tax Rate vs. Effective Tax Rate A progressive marginal tax applies only to income above a threshold — not to total income. This is critical: Basu's argument is about the top marginal rate, not a flat wealth confiscation.

Relative Income Hypothesis Economists like Robert Frank and Richard Easterlin have shown that beyond a certain income level, relative position matters more than absolute wealth — supporting Basu's claim that high marginal taxes won't kill incentives.

Inequality → Democratic Erosion The capture of media and information platforms by the ultra-wealthy creates what political scientists call "plutocratic drift" — where formal democracy persists but substantive voice is unequal.


India-Specific Relevance

  • India abolished wealth tax in 2015; estate duty was abolished in 1985.
  • The surcharge on high incomes (up to 37% on income above ₹5 crore) is India's closest existing instrument to Basu's proposal — but critics argue it is insufficient.
  • The K-shaped recovery post-COVID deepened inequality: corporate profits recovered sharply while real wages for the bottom half stagnated.
  • OXFAM India (2023) reported that 5 richest Indians could fund India's entire education and health budget for several years — illustrating the concentration Basu addresses.
  • India's digital media ownership is increasingly concentrated, raising concerns about the plurality of public discourse that López-Calva's framework highlights.

Challenges & Counterarguments

Against higher progressive taxation:

  • Risk of capital flight to low-tax jurisdictions (Singapore, UAE, Mauritius)
  • Definitional complexity — distinguishing income from capital gains, carried interest, stock options
  • Administrative capacity — India's tax administration struggles with existing compliance; adding complexity may reduce effectiveness
  • Potential disincentive for entrepreneurship if poorly designed

In favour:

  • IMF (2021) research shows moderate increases in top marginal rates do not significantly reduce growth
  • Revenue generated can fund human capital investment — education, health — which itself raises long-run productivity
  • Addresses political economy risks of unchecked plutocracy

Conclusion

Kaushik Basu's prescription — steeper progressive taxation on the very wealthy, combined with redistribution — is not radical by historical standards; the US top marginal rate was 91% in the 1950s during a period of robust growth. The deeper insight is that inequality today is no longer just an economic problem: it is a governance and democratic challenge, as wealth increasingly buys institutional influence rather than just goods. For India, the policy imperative is dual — redesigning the tax structure to be more progressive at the top, while simultaneously strengthening the trust infrastructure of the state through universal public services, credible institutions, and open civic space. Inequality left unaddressed does not merely slow growth; it erodes the social contract itself.

Quick Q&A

Everything you need to know

Progressive taxation refers to a tax system in which the tax rate increases as the taxable income rises, placing a higher burden on those with greater ability to pay. As highlighted by Kaushik Basu, such a system can be designed to impose higher taxes only on marginal income above a certain threshold, rather than on total income. This ensures that basic incentives for wealth creation remain intact while targeting excessive concentration of wealth.

The primary objective of progressive taxation is to reduce income inequality by redistributing wealth through public spending. The additional revenue generated can be used for welfare schemes such as healthcare, education, and social protection, thereby improving the living standards of lower-income groups. For example, countries like Sweden and Denmark have effectively used progressive taxation to maintain low inequality while sustaining economic growth.

Importantly, Basu argues that among the super-rich, competition is often driven by relative status rather than consumption needs. Therefore, higher marginal taxes may not significantly distort incentives, as individuals continue to compete within their peer group. Thus, progressive taxation emerges as a balanced tool that supports both economic efficiency and social equity.

Rising inequality in the digital economy poses unique challenges because it extends beyond wealth accumulation into the domain of information control and public discourse. As Basu points out, unlike in the past when wealth was spent on physical assets like mansions or yachts, today’s super-rich often acquire digital platforms and media networks, thereby influencing narratives and shaping public opinion.

This concentration of control can lead to a “silencing effect” on ordinary citizens, undermining democratic values such as free speech and equal representation. When a few individuals or corporations dominate digital spaces, the diversity of viewpoints diminishes, potentially leading to biased information ecosystems. For instance, global debates around social media regulation and platform monopolies—such as those involving Meta or X (formerly Twitter)—highlight these concerns.

Moreover, inequality can erode social cohesion by fostering perceptions of unfairness and exclusion. When large sections of society feel marginalized, it weakens trust in institutions and democratic processes. Therefore, addressing digital inequality is not merely an economic issue but a political and societal imperative essential for sustaining inclusive and participatory democracies.

Trust is a foundational element of any functioning economy, as it underpins the willingness of individuals and institutions to engage in transactions. According to the article, many economic activities rely on the expectation that parties will honour commitments. This reduces transaction costs, minimizes the need for excessive regulation, and facilitates smoother market operations.

When trust weakens, the consequences can be far-reaching. Businesses may become reluctant to invest, consumers may reduce spending, and financial institutions may tighten credit. For example, during the 2008 global financial crisis, the collapse of trust between banks led to a credit freeze, severely impacting global economic activity.

At a broader level, trust is also essential for institutional stability. Citizens must विश्वास in governments to deliver public goods and enforce rules fairly. If this trust erodes, it can lead to reduced compliance with laws, lower tax morale, and increased social unrest. Therefore, maintaining trust requires transparent governance, accountability, and consistent policy implementation, making it a critical pillar of both economic growth and democratic governance.

Higher taxation on the super-rich is often advocated as a means to address inequality, but its effectiveness must be evaluated from multiple perspectives. On the positive side, such taxation can generate substantial revenue for public welfare and reduce wealth concentration. As Basu argues, since the super-rich are driven by relative competition, higher marginal taxes may not significantly reduce their incentives to earn.

However, there are potential drawbacks. Critics argue that excessive taxation could lead to capital flight, tax evasion, or reduced investment, particularly in a globalized economy where capital is highly mobile. For instance, some high-net-worth individuals have relocated to low-tax jurisdictions in response to stricter tax regimes in countries like France.

A balanced approach is therefore necessary. Effective implementation requires robust tax administration, international cooperation to prevent tax avoidance, and careful calibration of tax rates. Additionally, taxation alone cannot solve inequality; it must be complemented by policies such as education, skill development, and job creation. Thus, while progressive taxation is a powerful tool, its success depends on broader institutional and policy frameworks.

Rebuilding public trust requires governments to deliver tangible outcomes that improve citizens’ lives. As highlighted by the World Bank perspective in the article, trust is strengthened when people see visible improvements in employment, public services, and social protection. For instance, India’s implementation of schemes like MGNREGA and Direct Benefit Transfers (DBT) has enhanced transparency and reduced leakages, thereby improving trust in welfare delivery.

Internationally, initiatives such as the World Bank’s efforts to expand electricity access in Africa and improve healthcare systems demonstrate how institutional interventions can build credibility. These programs not only address immediate needs but also signal the state’s commitment to inclusive development.

Another key aspect is strengthening democratic institutions. According to López-Calva, trust depends on four pillars: credible elections, political representation, civic space, and public debate. For example, countries with strong electoral systems and independent media, such as Canada, tend to exhibit higher levels of public trust. Thus, a combination of effective governance, inclusive policies, and institutional integrity is essential for rebuilding trust.

Designing a strategy for inclusive growth requires a multi-dimensional approach that addresses both economic disparities and institutional weaknesses. First, implementing a progressive taxation system can generate resources for redistribution without undermining economic incentives. These resources should be channelled into universal welfare programs such as healthcare, education, and social security.

Second, the strategy must focus on job creation and economic opportunities. Investments in infrastructure, green industrialization, and support for small and medium enterprises (SMEs) can drive employment and reduce inequality. For example, India’s Production-Linked Incentive (PLI) scheme aims to boost manufacturing while creating jobs.

Third, rebuilding trust requires strengthening institutions and ensuring transparency. This includes conducting free and fair elections, promoting civic participation, and maintaining an open public discourse. Additionally, leveraging technology for governance—such as digital platforms for service delivery—can enhance efficiency and accountability.

Way forward: A holistic approach combining economic reforms, social policies, and institutional strengthening is essential. By aligning growth with equity and trust, policymakers can create a sustainable and inclusive development model.
