"I am trying to put the distributional question and the study of long-run trends back at the heart of economic analysis. In that sense, I am pursuing a tradition which was pioneered by the economists of the 19th century, including David Ricardo and Karl Marx. One key difference is that I have a lot more historical data. With the help of,, Facundo Alvaredo, Gilles Postel-Vinay, Jean-Laurent Rosenthal, Gabriel Zucman and many other scholars, we have been able to collect a unique set of data covering three centuries and over 20 countries. This is by far the most extensive database available in regard to the historical evolution of income and wealth. This book proposes an interpretative synthesis based upon this collective data collection project."

“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.”

“Let it be said at once: Trump’s victory is primarily due to the explosion in economic and geographic inequality in the United States over several decades and the inability of successive governments to deal with this.”

“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.”

“The tragedy is that Trump’s program will only strengthen the trend towards inequality.”

“Ceta, the EU-Canada free trade deal, should be rejected. It is a treaty which belongs to another age. This strictly commercial treaty contains absolutely no restrictive measures concerning fiscal or climate issues. It does, however, contain a considerable reference to the “protection of investors”. This enables multinationals to sue states under private arbitration courts, bypassing the public tribunals available to one and all. The legal supervision proposed is clearly inadequate, in particular concerning the key question of the remuneration of the arbitrators-cum-referees and will lead to all sorts of abuses. At the very time when American legal imperialism is gaining in strength and imposing its rules and its dues on our companies, this decline in public justice is an aberration. The priority, on the contrary, should be the construction of strong public authorities, with the creation of a prosecutor, including a European state prosecutor, capable of enforcing their decisions.”

“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.”
