Thomas Piketty Quotes

There should be no more signing of international agreements that reduce customs duties and other commercial barriers without including quantified and binding measures to combat fiscal and climate dumping in those same treaties.

Democracy will never be supplanted by a republic of experts – and that is a very good thing.

I can now present the first fundamental law of capitalism, which links the capital stock to the flow of income from capital. The capital/income ratio β is related in a simple way to the share of income from capital in national income, denoted α. The formula is

In many ways, the US led the world toward the development of progressive taxation and the reduction of inequality at the global level during the first half of the 20th century... Unfortunately, one century later, in 2019, the rise of inequality creates new threats to liberal democracies. It is time to take a new step and to develop new policy instruments, in line with the challenges raised by global wealth trends.

The overall importance of capital today, as noted, is not very different from what it was in the eighteenth century. Only its form has changed: capital was once mainly land but is now industrial, financial, and real estate. We also know that the concentration of wealth remains high, although it is noticeably less extreme than it was a century ago. The poorest half of the population still owns nothing, but there is now a patrimonial middle class that owns between a middle and a third of total wealth, and the wealthiest ten percent now own only-two thirds of what there is to own rather than nine-tenths.

Capital is defined as the sum total of nonhuman assets that can be owned and exchanged on some market.

The distribution of wealth is one of today’s most widely discussed and controversial issues. But what do we really know about its evolution over the long term? Do the dynamics of private capital accumulation inevitably lead to the concentration of wealth in ever fewer hands, as Karl Marx believed in the nineteenth century? Or do the balancing forces of growth, competition, and technological progress lead in later stages of development to reduced inequality and greater harmony among the classes, as Simon Kuznets thought in the twentieth century? What do we really know about how wealth and income have evolved since the eighteenth century, and what lessons can we derive from that knowledge for the century now under way?

We know something about billionaire consumption, but it is hard to measure some of it. Some billionaires are consuming politicians, others consume reporters, and some consume academics.

Whenever the rate of return on capital is significantly and durably higher than the growth rate of the economy, it is all but inevitable that inheritance (of fortunes accumulated in the past) predominates over saving (wealth accumulated in the present). ... The inequality r > g in one sense implies that the past tends to devour the future: wealth originating in the past automatically grows more rapidly, even without labor, than wealth stemming from work, which can be saved. Almost inevitably, this tends to give lasting disproportionate importance to inequalities created in the past, and therefore to inheritance.

It is time to change the political discourse on globalization: trade is a good thing, but fair and sustainable development also demands public services, infrastructure, health and education systems. In turn, these themselves demand fair taxation systems. If we fail to deliver these, Trumpism will prevail.

National income is defined as the sum of all income available to the residents of a given country in a given year, regardless of the legal classification of that income.

How do wealth- and capital-output ratios evolve in the long run, and why? Until recently it was difficult to properly address this question, for one simple reason: national accounts were mostly about flows, not stocks. Economists had at their disposal a large body of historical series on flows of output, income and consumption – but limited data on stocks of assets and liabilities. When needed, for example for growth accounting exercises, estimates of capital stocks were typically obtained by cumulating past flows of saving and investment. This is fine for some purposes, but severely limits the set of questions one can ask.

Broadly speaking, the rise of the supermanager is largely an Anglo-Saxon phenomenon.

The main lesson for Europe and the world is clear: as a matter of urgency, globalization must be fundamentally re-oriented. The main challenges of our times are the rise in inequality and global warming. We must therefore implement international treaties enabling us to respond to these challenges and to promote a model for fair and sustainable development. Agreements of a new type can, if necessary, include measures aimed at facilitating these exchanges. But the question of liberalizing trade should no longer be the main focus. Trade must once again become a means in the service of higher ends. It never should have become anything other than that.

To put it bluntly, the discipline of economics has yet to get over its childish passion for mathematics.
