This is one of a series of posts that will ask what the most pertinent question raised by a prominent influencer of\u00a0political economy<\/a>\u00a0might have been, and what the relevance of that question might be today. There is a list of all posts in the series at the end of each entry. The\u00a0origin of this series is noted here.<\/a>\u00a0<\/em><\/p>\n

After the first two posts in this series, the topics have been chosen by me, and this is one of those. This series has been produced using what I describe as directed AI searches to establish positions with which I agree, followed by final editing before publication.\u00a0<\/em><\/p>\n

This post refers to\u00a0<\/em>Thomas Piketty<\/em><\/a>, the French economist whose most notable book is Capital in the Twenty-First Century. <\/a>In this, Piketty studied wealth and income inequality in Europe and the United States since the 18th century. The book was first published in French (as Le Capital au XXIe<\/sup>\u00a0si\u00e8cle<\/i>) in August 2013. An English translation\u00a0followed in April 2014.<\/em><\/span><\/p>\n

Why is Thomas Piketty in this series? Firstly, because he tackles a key issue in our time: inequality. Second, because he showed (at length) that this was not inevitable, or a passing phenomenon, but was instead an obvious political construct that did, as a result, require political correction if the problems it gave rise to are to be addressed, which he argued they must be. Third, because he demonstrates the use of tax as a policy instrument, which matters to me. And, fourth, the discussion of Piketty follows logically from the discussion of John Rawls<\/a>, who was the subject of the immediately preceding essay in this series.\u00a0<\/em><\/p>\n

Thomas Piketty\u2019s Capital in the Twenty-First Century<\/i> (2013) was a bomb dropped into the polite world of economics. It did not rely on theory. It relied on data \u2014 two centuries of it, painstakingly compiled from tax records, national accounts, and inheritance registers. What Piketty showed was that inequality is not an accident of policy or a passing phase of development. It is a structural feature of capitalism itself.<\/p>\n

His central equation,\u00a0that\u00a0r > g, <\/em><\/span>captured that truth in a simple inequality. His argument is that when the rate of return on capital (r<\/i>) exceeds the rate of economic growth (g<\/i>), wealth accumulates faster than incomes rise. Those who already own assets grow richer, while those who rely on wages fall behind. Over time, inequality does, then, become self-perpetuating.<\/p>\n

This was not a Marxist argument about exploitation. It was a statistical description of what capitalism does when left to its own devices. Piketty\u2019s conclusion was unambiguous: without deliberate political intervention through progressive taxation, redistribution, and public investment, inequality will spiral until it undermines democracy itself.<\/p>\n

Hence the Piketty Question<\/span>: if we now know that capitalism naturally produces inequality faster than growth can correct it, why do we still design policies that entrench it?<\/i><\/i><\/p>\n

The empirical revolution<\/b><\/p>\n

Before Piketty, inequality was treated as a moral or political question, not an empirical one. Economists assured us that as countries grew richer, inequality would first rise and then fall, as the Kuznets curve<\/a> suggested. Piketty demolished that myth.<\/p>\n

His historical data showed that the post-war reduction in inequality was exceptional, not normal. It had occurred only under the extraordinary conditions of World War II, the reconstruction that followed, an era of high inflation, and deliberate redistribution policies. As he showed, since the 1980s, as those policies have been reversed, inequality has returned to nineteenth-century levels.<\/p>\n

The lesson is clear: left to its own devices, capitalism does not deliver equality. It delivers concentration.<\/p>\n

The politics of the return<\/b><\/p>\n

Piketty's suggestion is that capital begets capital, wealth generates income, and income buys influence. Those with wealth accumulate not only assets but also power over politics, the media, and public discourse.<\/p>\n

His research showed that wealth concentration is not just an economic process but a political one. The wealthy use their power to reduce taxes, weaken regulation, suppress unions, and shape ideology. They fund think tanks and media outlets that promote the very policies that entrench their dominance.<\/p>\n

In other words, inequality is not only the outcome of markets; it is the design of politics.<\/p>\n

The myth of merit<\/b><\/p>\n

One of Piketty\u2019s most devastating insights was to show how inequality hides behind moral language. Today\u2019s elite like to claim that their wealth reflects talent and hard work. But the data say otherwise. Inherited wealth is once again the dominant factor determining life chances. \u201cMeritocracy\u201d has become a self-serving fiction, masking the return of patrimonial capitalism.<\/p>\n

When wealth reproduces itself through inheritance rather than innovation, societies ossify. Social mobility collapses. Democracy becomes plutocracy.<\/p>\n

The international dimension<\/b><\/p>\n

Piketty\u2019s work also reveals the global dimension of inequality. The same forces that concentrate wealth within nations also concentrate it between them. Capital now flows freely across borders, while labour is constrained. The result is a global system in which wealth accumulates in the financial centres of the rich world \u2014 and in the secrecy jurisdictions that serve them \u2014 while the developing world is drained of resources and talent.<\/p>\n

This is not merely the outcome of market forces. It is the architecture of global capitalism \u2014 designed, maintained, and defended by those who benefit most from it.<\/p>\n

Why policy fails<\/b><\/p>\n

If Piketty has made the mechanics of inequality so visible, why do governments not act? The answer lies in capture. Politics is increasingly financed by the wealthy. Parties compete for donors, not for voters. The revolving door between finance and government ensures that reform never threatens the system\u2019s foundations.<\/p>\n

Even centre-left governments, fearful of market reaction, have accepted the limits set by capital. The result is a politics that talks of fairness while quietly perpetuating inequality.<\/p>\n

Piketty\u2019s unfinished agenda<\/b><\/p>\n

Piketty\u2019s own solutions were moderate but radical in implication. They include:<\/p>\n
