Really great to see this: six Nobel Prize-winning economists (Duflo, Krugman, Diamond, Banerjee, Acemoglu and Stiglitz) just came out in favor of the California billionaire tax. You don't have to be a radical leftist to see why it's a good idea. First, look at the numbers: ten years ago, the richest 0.001% of Californians were worth $700 billion. Today, that same group (about 250 people) is worth $2.3 trillion. From 2019 to 2025, their wealth grew by $1.4 trillion. The California income tax they paid over that period was just 1.6% of that gain. A nurse or a plumber pays a higher state tax rate. Yes, many of these people built great companies, and they've made a lot of money in the process. Good for them! The problem is that wealth on this scale stops being just money. It becomes extraordinary power. In 2000, billionaires accounted for about 1% of all donations in federal elections. In 2024, it was 19%. The Washington Post, the Wall Street Journal, the LA Times, Facebook, Instagram, TikTok and the platform you're reading this on: all owned and controlled by billionaires. Now add AI. If you think power is concentrated now, just wait five years. It's going to get much worse. So, what does Prop 40 actually do? It's a one-time 5% tax on the wealth of California's billionaires. That would raise about $100 billion, enough to offset the federal Medicaid cuts. "But they'll all leave!" the critics say. Nope, they can't. The tax applies to any billionaire who lived in California on January 1, 2026, and the initiative only became public about five weeks before that. "But it'll kill Silicon Valley!" Uh no, that won't happen either. Since the tax was announced, California's share of all new US venture capital has gone up, from about 50% to 80%. Nvidia CEO Jensen Huang, who would be one of the biggest payers, said he would be "perfectly fine" with it and had "not even thought about it once". Sure, some other billionaires can't stop thinking about it. Sergey Brin has already spent more than $100 million to defeat the proposal. At a holiday party in December he pulled Gavin Newson aside and said 'he could not stand the state’s proposed billionaire tax', because he thought the 5% tax would turn California into some kind of Soviet Union. That is, of course, nonsense. This is not going to be some kind of socialist revolution. The proposal is about restoring balance to a mixed economy. You could even argue it's about saving capitalism itself from oligarchs like Sergey Brin. I think that's exactly why Nobel Prize-winning economists are coming out in favor of this tax. If Prop 40 passes in November, it will be the first tax aimed specifically at billionaire wealth anywhere in the world. I think it could be the start of a global movement. Anyway, read the whole letter here. It's really good 👇 gabriel-zucman.eu/files/prop…

MAGA Republicans voted for the most extreme Republican candidates in the primaries. Some ate even indicted criminals like Paxton.

The ‘small boats’ have now become the big boats.

Still gripped by @TheRapture @BBCOne from @LizJensen’s incredibly creepy dystopian clifi novel. But also wondering why there are no wheelchairs that could raise disabled people to eye-level instead of infantilising them at waist height?

The only one I can find looking through archives is this one from the 1988 WI tour of England taken at The Oval

It has nothing to do with DEI policies. I've always esteemed your work, but frankly when you come to write about Britain, I think you depart from your own high standards

Big Money campaign contributions are destroying American democracy. Today, Rep. Summer Lee and I are introducing legislation to end billionaire-funded super PACs. Democracy means one person, one vote. We must not allow oligarchs to buy elections.

Happy pub day to Andrew Miller and his dazzling, Booker-shortlisted novel, THE LAND IN WINTER!

‘Enough is Enough’ coordinated by Yaxley-Lennon and promoted by Laurence Fox?

Absolutely amazing brand awareness that Bishop’s Move have parked diagonally.

Q for political scientists I'm falling for the French voting system (1st round, vote (ish) for your main preference; 2nd round, be forced to decide between front runners). Am I being hopelessly naive?

Thank you to the lovely @ScottishLabour voters on the Irvine🚂 who wished me well for my first day in the new job! Sorry I was rushing for a very special start to the week with @AnasSarwar and Prime Minister @Keir_Starmer.
