Summary of: The Economics of Inequality
By: Thomas Piketty


Welcome to our summary of ‘The Economics of Inequality’ by Thomas Piketty, where we will unravel the complex notions of income inequality and redistribution among Western nations. We will examine the various taxation systems, redistributive measures, labor incomes, and the impact of capital versus labor on economic growth. The summary also delves into the importance of education, health care spending, and the effects of globalization on income disparities. Thomas Piketty presents invaluable insights into understanding the root causes and consequences of economic inequality and potential pathways for effective redistribution strategies.

The Illusion of Inequality

When comparing inequality levels among Western nations, it’s important to consider their different labor classifications, taxes, and redistribution policies. Governments use various methods for fiscal redistribution, including taxes, social transfers, and subsidizing education and health care. Although it may seem like French employers pay a higher proportion of their output to labor than their Danish counterparts, the reality is that employees pay for all employer taxes. French employees don’t pay taxes on income from social transfers but take home only a portion of their gross salary, while Danish wage earners receive their full wages but pay individual taxes on all sources of income, including government transfers. Therefore, workers in France and Denmark earn equivalent wages despite the different tax and transfer regimes. Nordic countries apply an income tax to pensions and other social program income, which artificially increases their income tax percentage relative to GDP by 10%. However, this practice doesn’t result in substantial fiscal redistribution. Overall, it’s essential to analyze and understand different factors that contribute to inequality levels among Western nations to avoid drawing inaccurate conclusions.

The Stability of Capital and Labor Share

The balance of the economy’s proceeds between capital and labor has remained steady over generations. The increase in workers’ income and productivity comes from economic and productivity growth, not from gaining ground against capitalist business owners. Taxing capital excessively can hurt a country’s productivity and negatively affect workers’ standard of living. Most of the growth in inequality in developed countries comes from the widening gaps in labor incomes, with self-selection accounting for almost half the increase in inequality in the US between 1970 and 1990. Education spending, progressive income taxes, fiscal transfers, and minimum wage rates are government measures that could reduce inequality.

The economy’s proceeds have been consistently divided between capital and labor at around one-third and two-thirds, respectively, over generations, with capital’s share slightly on the rise. Workers’ income increases in rich countries come from economic and productivity growth, not from gaining ground against capitalist business owners. Taxing capital excessively can hurt a country’s productivity and workers’ standard of living in the long run. Inequality in developed countries comes from widening gaps in labor incomes, where the top-earners capture more of an economy’s output than low earners. Self-selection is also a major factor, with social selection accounting for nearly half the increase in inequality in the US between 1970 and 1990. To reduce inequality, government measures, such as education spending, progressive income taxes, fiscal transfers, and minimum wage rates, could be implemented.

Tackling Income Inequality

A market economy relies on clear prices for labor and capital to function efficiently. Government policies aimed at reducing inequality could distort free market prices, resulting in unintended effects. Efforts to combat labor income inequality can involve high minimum wages or union pressures, leading to employers substituting mechanization or reducing employment. Free market economist Milton Friedman proposed a universal basic income as a remedy to distortion concerns, allowing the less well-off to participate in the job market without altering incentives or distorting wages.

Tackling Economic Inequality

Left-leaning Solutions for Economic Inequality

Experts on the left often advocate for nationalization and greater union power to address economic inequality instead of relying solely on taxation and direct transfers. While these remedies may ultimately reduce the demand for labor, these experts point out that countries with steady declines in union membership have seen the most severe increases in inequality since the 1980s. Unions can improve communication between employers and workers and provide organized wage schedules that encourage employees to invest in their skills. High union-mandated wages can also substitute for government social programs.

Some economists are against raising minimum wages due to possible market distortions. However, studies have proven that increasing minimum wages has not negatively impacted unemployment rates. In fact, it has increased labor participation rates when the previous minimum wage was exceptionally low.

The best approach to reducing inequality in the capitalist market is to let free labor market prices produce optimum results reflecting labor productivity. However, governments must use taxation and spending to counteract the natural unequal rewards of a capitalist market. To achieve this, taxes on low-skilled and semiskilled labor, and taxes that make this labor more expensive for employers, should be minimized, while taxes on capital profits and top earners could be raised. By implementing these solutions, society can create a more equal labor market.
