The era of trillionaires will be dire for democracy. Here is how we can fight back | Gabriel Zucman

In bookstores across the US on August 25. If ever there was a time to act, it is now.

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

Saez and @gabrielzucman.bsky.social on the CA billionaire tax 250 households (0.001% of the state) holds wealth equal to more than half of California’s entire annual economic output Their wealth grows 15% a year and is taxed at just 0.26% per year www.nytimes.com/interactive/...

Le temps est venu de taxer les profiteurs de guerre. open.substack.com/pub/gabrielz...

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. open.substack.com/pub/gzucman/...

It was a wonderful event at @thegraduatecenter.bsky.social today with an enthusiastic and packed house to hear @gabrielzucman.bsky.social, @mayor.nyc.gov and I talk about the absolute necessity for global societies to tax the ultra rich. It's not radical to think they should pay their fair share too

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

Over 80% of people want a wealth tax for billionaires. Of course they’re resisting with their army of lawyers and lobbyists, but we’re building ours. I’m so excited to be teaming up with @gabrielzucman.bsky.social 👉

En la década de los setenta, el 90 % de la renta obtenida del petróleo se socializaba. Hoy en día, dos tercios terminan en los bolsillos de los accionistas. 📈 Un análisis del economista @gabrielzucman.bsky.social ctxt.es/es/20260401/...

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. gabrielzucman.substack.com/p/ou-vont-le...

Brussels bubble: "the US is pulling ahead, the EU is lagging behind and must deregulate to remain competitive" Reality:

Ces dernières semaines, je suis allé dans plusieurs pays européens et j’ai des bonnes nouvelles à vous annoncer.🧵

Un grand merci aux étudiants de la Sorbonne et de l'ENS venus nombreux pour parler de justice fiscale et de démocratie La tournée de conférences publiques continue : à l'université de Nantes le 7 avril, à l'Alcazar de Marseille le 11 avril... A très bientôt partout en France!

The pace at which US wealth concentration is rising is simply staggering The concentration of AI wealth into the hands of a few tech barons + plutocratic capture ==> unchartered territory

In bookstores in the UK on May 21 Very much looking forward to this

1/ Big news! Today, we officially launch the International Tax Observatory (#ITO)🚀 Building on the foundation of the EUTO, we are expanding our mission to address global tax evasion, wealth concentration, illicit financial flows & the intersection of taxation & the environment.

Thank you Intertax for this special issue on the billionaire tax I have proposed, with lots of sharp and insightful contributions to the debate taxprofblog.aals.org/2026/01/31/i...

For two days, French star economist Gabriel Zucman was in the Netherlands. We followed him for #Nieuwsuur (yes, even on a bike! ) to hear why the super-rich should pay more tax, in our country too. Watch our report with @gabrielzucman.bsky.social ⬇️ nos.nl/l/2600719

Très honoré d’avoir reçu ce soir ce prix de l’association Anticor Le temps est venu de taxer les milliardaires, et de mettre en conformité nos lois avec nos principaux fondamentaux d’égalité devant l’impôt.

We hear it all the time: Since the turn of the 2010s, thanks to the rise of tech, the US has pulled ahead economically. This idea is everywhere from Washington to Davos—and it's paralyzing Europe But it's simply not true! Let's look at what's really happening, with charts🧵

Wochenendlektüre. @gabrielzucman.bsky.social

De econoom Gabriel Zucman (@gabrielzucman.bsky.social) geeft 2 februari om 17:00 een lezing in het splinternieuwe Spuigebouw in Den Haag: Taxing the ultra-rich: public finance in an age of extreme inequality. De lezing is openbaar maar aanmelden is verplicht en kan via [email protected].

Op 29 januari komt het nieuwe essay van @gabrielzucman.bsky.social in het Nederlands uit: Miljardairs betalen geen inkomstenbelasting en daar gaan we een eind aan maken. Wat mij betreft een absolute aanrader voor iedereen die geïnteresseerd is in ongelijkheid, belastingen en onze democratie.

Ich bin begeistert von der Veröffentlichung dieses Buches und freue mich darauf, später in diesem Monat in Berlin darüber zu sprechen.

California wants to tax billionaires with a 5% wealth tax and the CEO of Nvidia, who would have to pay $8 billion on his $163 billion fortune, says it like it is: that's perfectly fine! 🧵

It has become received wisdom in Brussels and Washington that there is a new “euro-sclerosis”: that the EU economy is lagging the US This view is wrong A little primer on the measurement of productivity – and why reports of the economic death of Europe are greatly exaggerated🧵

Un grand merci aux aixoises et aux aixois d'être venus si nombreux à Sciences Po pour parler de l'avenir de la justice fiscale et de la démocratie. La tournée de conférences publiques se poursuivra en 2026 dans toute la France -- à très bientôt !

400 personnes à la Librairie des Volcans, plus de 1 000 à la faculté, toutes curieuses de s’approprier les savoirs, de réfléchir aux nouveaux horizons de la démocratie : C’est à Clermont-Ferrand que la grande bataille citoyenne pour la justice fiscale a commencé 🧵

Aujourd’hui sort mon nouveau livre «Les milliardaires ne paient pas d’impôt sur le revenu et nous allons y mettre fin.»🧵

Je me réjouis grandement de débattre avec Pascal Saint-Amans le jeudi 23 octobre à 9h à l'Ecole normale supérieure, autour de la parution de mon livre "Les milliardaires ne paient pas d'impôt sur le revenu et nous allons y mettre fin" Inscriptions 👇👇👇 www.ens.psl.eu/actualites/t...

Opinion: More than any other western European country, France is dominated by powerful billionaires paying relatively low taxes. Most voters agree that France should cut its deficit, and the majority says: the super-rich first. on.ft.com/4hedHHZ

Tout juste sortis de l'imprimerie. En librairie le 24 octobre. Très hâte !

Parfois c’est ce qui nous est le plus proche que l’on met le plus de temps à voir. Pendant quinze ans j’ai cartographié les grandes fortunes mondiales, objectivé leurs techniques pour contourner l’impôt dans les paradis fiscaux, du Luxembourg aux îles vierges britanniques... 🧵

🚨New working paper🚨 In this updated work with Annette Alstadsaeter, @bluebery-planterose.com , @gabrielzucman.bsky.social and @andokl.bsky.social , we use leaked data to chart the rise of offshore real estate in Dubai www.taxobservatory.eu//www-site/up...

Matching the Forbes 400 to tax data finds that they pay a total tax rate of 24 percent of economic income, lower than the 30 percent tax rate paid on average in the US, from Akcan S. Balkir, Emmanuel Saez, Danny Yagan, and Gabriel Zucman https://www.nber.org/papers/w34170

New Bureau of Economic Analysis data: In 2023 US multinationals booked 42% of their foreign profits in the main tax havens After 2 years of unprecedented decline, profit shifting seems to be rising again Back to the lung-run trend that started in 1978?

Think how much you pay in taxes. Now think about this: The ultra-wealthy pay between 0% and 0.6% of their wealth in individual income tax – around 0.6% in a country like the United States and 0.1% in a country like France. We wrote about it in @lemonde.fr www.lemonde.fr/en/opinion/a...

An international call for action just got louder: Today, 7 Nobel Laureates have issued a powerful call for a minimum tax on the ultra-wealthy in Le Monde Here’s a quick breakdown of the debate—and where things stand globally 🧵 www.lemonde.fr/en/opinion/a...
