New paper on wid.world by @gatonievas & @PaulaDruschke finds that 70% of World Bank and IMF funds are allocated to G7 geopolitically aligned countries.
Militaristic drift, admission of weakness
The militaristic drift of the United States resonates above all as a terrible admission of weakness in the face of the financial, commercial and political fragility of the country

Dérive militariste, aveu de faiblesse
La dérive militariste des Etats-Unis résonne comme un terrible aveu de faiblesse face à la fragilité financière, commerciale et politique du pays

Congrats Bernie Sanders & Ro Khanna for this new bill proposing a 5% federal wealth tax on billionaires
Together with upcoming California wealth tax referendum to fund public health care, this is putting the US back at the center of global justice debate

Europe, a social-democratic power
To win the cultural and intellectual battle, Europe must now assert its values and defend its model of development, fundamentally opposed to the nationalist-extractivist model of Trump and Putin

L'Europe, puissance sociale-démocrate
Pour gagner la bataille culturelle et intellectuelle, il est temps que l’Europe affirme ses valeurs et défende haut et fort son modèle de développement, opposé en tous points au modèle nationaliste-extractiviste

L'Europe a une productivité égale ou supérieure au niveau US depuis des décennies, grâce aux investissements dans la formation, la santé et les infrastructures. Il faut sortir de l'auto-dénigrement & investir davantage!

Project 2025: from nightmare to reality
To better understand what made the Trump shock possible, and how to confront it in the future, we must turn to its roots, namely, to Project 2025

Project 2025, du cauchemar à la réalité
Pour mieux comprendre ce qui a rendu possible le choc Trump et comment y faire face à l’avenir, il faut commencer par revenir aux sources, c’est-à-dire au Project 2025

Moralité: si l'Europe ne sort pas urgemment du régime de sacralisation de la propriété privée et de libre-échange absolu mis en place dans les 1990s, on ne pourra jamais résoudre les défis géopolitiques, sociaux, industriels et climatiques du 21e siècle

C'est bien de verser une larme sur la taxe foncière... ce serait encore mieux de rappeler que la TF est passée de 30 à 50 milliards € de 2010 à 2025... c'est dommage d'avoir refusé l'impôt de 2% sur les ultrariches (20 milliards)

Today, I joined 500+ researchers from 70 countries in calling on world leaders to create an International Panel on Inequality modelled after the IPCC— as recommended by the G20 Committee on Inequality led by @JosephEStiglitz. Help us spread the call.

Le Pen’s RN has become the party of billionaires
By voting to save the ultra-rich, the RN has clearly positioned itself as the party of billionaires, as a right-wing party on every level, much like Trump’s Republican Party
wp.me/pgT76t-BT
Le RN, parti des milliardaires
En volant au secours des ultra-riches, le RN s’est clairement affirmé comme le parti des milliardaires, comme un parti de droite, sur tous les plans, de la même façon que les républicains de Donald Trump.

The decision by South African President @CyrilRamaphosa to place inequality at the heart of the G20 agenda is historic. It marks a significant step forward on the long road toward greater equality. It is no coincidence that countries from the Global South—Brazil and South Africa—…

In the long-run, equality & prosperity come together: the ratio P99.9/P10 dropped from 150 to <10 in Nordic countries, & this did not prevent them from becoming the most productive in the world
This is the path to follow for sustainable development

Rethinking world trade
When setting tariffs, Trump has followed a narrowly nationalist and rather chaotic logic. The opposite approach is needed: Tariffs should be set based on universal and predictable principles.

Repenser le commerce mondial
Pour fixer ses droits de douane, Trump a suivi une logique nationaliste et chaotique. Il faut faire tout le contraire : les droits de douane doivent être fixés sur la base de principes universalistes et prévisibles.

C'est un début... mais cela reste très insuffisant: il est temps d'imposer des sanctions drastiques sur les dirigeants politiques et le commandement militaire israéliens: saisie des avoirs et des biens, fin des visas, etc.

Many of our current political difficulties - not only in France but also in US UK Germany etc. - are due to the rising territorial divisions between the rural poor and the urban poor. Something we see in 19c & early 20c but was circumvented during 20c... & in 21c?

Two centuries of unequal exchanges

Ultra-wealthy, the Senate beside the story
By opposing the 2% minimum wealth tax on billionaires, the French Senate has shown just how disconnected it is from the issues of our time

Ultra-riches, le Sénat à côté de l'histoire
En s’opposant à l’impôt plancher de 2% sur les milliardaires, le Sénat vient de montrer à quel point il était déconnecté des enjeux de notre époque
