New working paper: the Norwegian wealth tax was a huge success. The "exodus" of wealthy people never happened (less than 100 individuals left). Tax revenue increased by 71.5%. No changes in business activity or investment.
💸 How does dirty money move across borders, and why is it so difficult to stop?
Join Oliver Bullough for #TheOffshoreTalks as he explores the hidden financial systems that allow illicit wealth to circulate, followed by a discussion with Sara Brimbeuf.
Billionaires want you to believe taxing their extreme wealth is too radical and that it can’t be done.
Baloney.
Economist @gabrielzucman.bsky.social debunks their lies. Watch.
Thanks Martin Wolf for including “We need to tax billionaires” in the FT’s best books of 2026 ✊
There's much more on realtimeinequality.org, which we just updated -- comments most welcome as always.
High profits (and expectation of future profits) are pushing top wealth shares past their Covid peak, to levels not seen since the early 20th century. Here's the top 0.1% wealth share.
The very fast growth at the top is linked to the explosion of corporate profits, now at an all time high relative to GDP.
It's hard not to view this as an important reason for the abysmal consumer sentiment (in spite of decent macroeconomic numbers).
Average income per adult grew 1.9% (net of inflation) in 2025. But for the bottom 50% there was no growth. And for the next 40% very little. Almost all the growth was concentrated in the top 10%.
It seems we are now entering a new phase of the rise of inequality in the US.
It's not just wealth and billionaires — it's a broader acceleration.
Here's who benefited from economic growth in 2025, according to the latest estimates available on realtimeinequality.org
Le temps est venu de taxer les profiteurs de guerre.
Where are the profits of the war going?
With the rise in oil prices, the profits of extractive companies surge—and a significant share ends up funneled through tax havens.
But it’s not too late to tax war profiteers effectively.
Happy tax day to all those who celebrate!
Couldn’t be more excited to be in New York on this day to discuss the global fight to tax the super rich with Mayor @zohrankmamdani.bsky.social and @josephestiglitz.bsky.social
"There is no justification for a regressive system in which the super-rich contribute less than the rest of us," write @josephestiglitz.bsky.social, @gabrielzucman.bsky.social, and @zohrankmamdani.bsky.social.
Où vont les profits de la guerre ?
Avec l’envolée des prix du pétrole, les bénéfices des sociétés extractives explosent et finissent recyclés dans les paradis fiscaux.
Mais il n’est pas trop tard pour taxer efficacement les profiteurs de guerre.
Brussels bubble: "the US is pulling ahead, the EU is lagging behind and must deregulate to remain competitive" Reality:
Ce n'est que le début. Mais c'est une lueur d'espoir pour 2026. Et je n’ai aucun doute que dans ce combat – la bataille capitale du 21e siècle – les forces de la démocratie finiront par triompher.
Cette alliance n’en est qu’à ses balbutiements. Mais de Pedro Sanchez en Espagne, à Lula au Brésil, en passant par Zack Polanski au Royaume-Uni ou AOC aux États-Unis, nous assistons peut-être à sa naissance aujourd’hui.
Une alliance pour inventer et mettre en œuvre les nouveaux principes — tel l’impôt plancher sur les ultra-riches – qui permettront aux forces démocratiques de l’emporter sur les forces ploutocratiques.
