Among the proposed solutions, the author mentions models that aim to directly tax wealth or reform the way capital gains and inheritances are taxed. He also cites as an example Senator Bernie Sanders’ proposal for a 5% annual tax on the wealth of billionaires, which, according to him, could generate more than $4 trillion in ten years.
In an analysis published in Project Syndicate, economist Michael Madowitz argues that the extreme concentration of wealth in the hands of a small number of individuals is posing a threat to American democracy and that a tax on large wealth is one way to curb this phenomenon.
Madowitz begins his analysis by referring to Elon Musk, who, after SpaceX went public, temporarily became the first person in the world with a fortune of one trillion dollars. According to him, Musk’s wealth has increased significantly since the 2024 presidential election, while the political influence of ultra-rich individuals has expanded in parallel with their economic power. According to the author, the 400 richest Americans now own wealth equivalent to about 20% of US Gross Domestic Product, a huge increase compared to 1982, when this figure was about 2%. Madowitz argues that the current American tax system favors the accumulation of wealth, since income from work is taxed more than the increase in the value of assets such as stocks, properties and inheritances. According to him, billionaires often avoid high taxation by taking out loans against their assets instead of receiving large salaries.
He cites the strategy known as “buy, borrow, die,” in which very wealthy individuals buy assets, borrow against them as collateral, and pass the wealth on to their heirs with tax advantages. According to the analysis, in the 1950s, the richest American families paid much higher effective tax rates, while in 2020, the 400 richest Americans had an average effective tax rate of 23.8%, lower than the national average.
Madowitz also links the concentration of wealth to political influence, arguing that US Supreme Court decisions that allowed unlimited spending on political campaigns have increased the influence of billionaire donors in electoral processes. He emphasizes that calls for “taxing the rich” are no longer just political slogans, but are supported by a large number of economic studies and concrete proposals. Among the proposed solutions, the author mentions models that aim to directly tax wealth or reform the way capital gains and inheritances are taxed. He also cites as an example Senator Bernie Sanders’ proposal for a 5% annual tax on the wealth of billionaires, which, according to him, could generate more than $4 trillion in ten years.
According to Madowitz, these funds could be used for public investments, expansion of health services, childcare, and economic support for middle- and low-income families.
The author challenges the traditional argument that tax cuts for the wealthy automatically bring benefits to society as a whole, stating that recent economic research has not found strong evidence for the expected effects of the “wealth-flow-from-top-down” theory. In conclusion, Madowitz argues that a reform of the tax system is not a radical measure, but a necessary correction to limit the excessive concentration of wealth and political influence. According to him, the main challenge is not a lack of ideas for a fairer system, but the political will to implement it before the economic power of a few continues to affect the functioning of democracy.
