The Unjust Tax System: A Global Crisis of Inequality
Tax day serves as a stark reminder of America's profoundly unequal tax system, but this is not an insurmountable problem. According to leading economists and policymakers, there is absolutely no justification for maintaining a regressive system where the super-rich contribute proportionally less than ordinary working citizens.
The Scale of Modern Inequality
Today, we face unprecedented levels of income and wealth inequality across the globe. Consider New York City, where the average household income stands at $131,000. Without extreme inequality, this would provide residents with a reasonable standard of living. Instead, a tiny elite at the top of the income ladder captures enormous wealth while millions struggle to make ends meet. For many, New York has become fundamentally unaffordable.
This outsized inequality carries enormous economic, political, and social consequences. It undermines social cohesion, erodes trust in institutions, and leads people to correctly conclude that the system is rigged against them.
A Global Phenomenon
While nearly one-fifth of America's super-rich reside in New York—representing the highest concentration of wealth in any state—inequality extends far beyond American borders. The United States exhibits more inequality than almost every other advanced economy, but this is truly a global crisis.
The Global Inequality Report, commissioned during South Africa's G20 presidency, revealed that between 2000 and 2024, the wealthiest 1% captured 41% of all new wealth globally, while the bottom half of humanity received just 1%. This trajectory is clearly unsustainable.
The rise of extreme wealth provides one of the clearest indicators of this imbalance. In 1987, billionaires held wealth equivalent to 3% of global GDP. Today, this minuscule elite—representing just 0.0001% of the world's population—owns wealth equal to 16% of global GDP.
The Taxation Failure
As wealth concentrates, so does power—the power to influence elections, shape policy, tilt markets, and define public discourse. One primary driver of this trend is our collective failure to effectively tax the super-rich.
Until recently, measuring the scale of this problem proved difficult because public data didn't track the tax contributions of the ultra-wealthy. However, recent research has produced clear findings: in the 1960s, the 400 richest Americans paid approximately 50% of their income in taxes across all government levels. Today, that figure has plummeted to about 24%.
This pattern isn't unique to the United States. Across Europe—including France, Italy, and the Netherlands—and in countries like Brazil, researchers have identified the same trend: the super-rich pay lower effective tax rates than almost everyone else. They excel not only at generating wealth but at avoiding and evading taxes.
Even when they do pay taxes, their contributions fall far short of their fair share, despite the fact that their wealth depends heavily on public investment: government contracts, educated workforces, legal systems that facilitate business, infrastructure, and even the basic technologies underlying their innovations. Instead, the burden shifts to working people whose taxes sustain the very systems that enable extreme wealth accumulation.
The Growing Reform Movement
For too long, tax reform has been dismissed as too complex or politically infeasible, despite voters across the political spectrum enthusiastically supporting the idea that the rich should pay what they owe. This is beginning to change dramatically.
In 2024, under Brazil's leadership, the G20 placed this issue on its agenda and committed to more effective taxation of ultra-high-net-worth individuals. The group commissioned a report proposing a minimum tax of 2% on the wealth of the super-rich—a straightforward mechanism to ensure they meet their societal obligations.
This powerful idea has created ripple effects worldwide. In 2025, Spain and Brazil committed to leading a coalition of countries to implement such measures. This weekend, Spanish Prime Minister Pedro Sánchez and Brazilian President Luiz Inácio Lula Silva will meet in Barcelona with the heads of state from South Africa, Mexico, Colombia, and numerous other nations to advance this agenda.
In France, a version of this minimum tax passed the National Assembly, though it was blocked by the conservative Senate. Nevertheless, it remains central to the national debate—much like the income tax itself, which once faced similar resistance before becoming law.
American Initiatives
In the United States, a paradigm shift is underway. California voters will consider a tax on billionaire wealth this November. Washington state has approved a 9.9% income tax on million-dollar incomes, scheduled to take effect in 2028. In New York, policymakers are calling for increased taxes on the wealthy and large corporations to close the city's budget deficit and fund essential public services like affordable housing and childcare.
Progress is already visible with New York City's new pied-à-terre tax, which will target ultra-wealthy individuals and global elites who maintain secondary residences in the city.
A Basic Social Principle
These developments represent just the first steps toward restoring a fundamental social principle: those with the most should contribute their fair share so that everyone can live with dignity.
The idea that billionaires should pay higher tax rates than working people is not radical. What is truly radical is allowing a system where extreme wealth coexists with widespread hardship—and where billionaires can effectively opt out of contributing to the societies that made their success possible.
The longer we delay addressing this imbalance, the more entrenched wealth and economic power become, further cementing the privileges of our modern aristocracy and deepening inequality for generations to come.
