A lot of young unemployed people have never had the chance of work. We need to help them break out of the no experience no job bind. Work experience can help do that and that's why we want more young people to have that chance. theguardian.com/society/2026/m…











A lot of time housebuilders get stick for failing to build 'the right number' of social houses as part of a development plan. It may help to get a little insight into how development economics works. You may find the below linked tweet interesting as well- it ties into what I am talking about here neatly: x.com/johndotwills/s…




In case you missed it: the Labour Government is getting on with bringing rail into public control - including GWR 🚄 This rail operator will be coming under public control on 13 December, and there are more to come!


“Let me say this really clearly. I support the fiscal rules. There needs to be a plan to get debt down, but beyond that, we need to change politics and take the turbulence out of British politics because that is a cause of uncertainty that then has that impact in the market” - Andy Burnham


Two economists just published a mathematical proof that AI will destroy the economy. Not might. Not could. Will — if nothing changes. The paper is called "The AI Layoff Trap." Published March 2, 2026. Wharton School, University of Pennsylvania. Boston University. Peer reviewed. Mathematically modeled. The conclusion is one sentence. "At the limit, firms automate their way to boundless productivity and zero demand." An economy that produces everything. And sells it to nobody. Here is how you get there. A company fires 500 workers and replaces them with AI. A competitor fires 700 to keep up. Another fires 1,000. Every company is behaving rationally. Every company is following the incentives correctly. And every company is building a trap for itself. Because the workers who were fired were also customers. When they lose their jobs faster than the economy can absorb them, they stop spending. Consumer demand falls. Companies respond by cutting costs — which means automating more workers — which means less spending — which means more falling demand — which means more automation. The loop has no natural exit. The researchers tested every proposed solution. Universal basic income. Capital income taxes. Worker equity participation. Upskilling programs. Corporate coordination agreements. Every single one failed in the model. The only intervention that worked: a Pigouvian automation tax — a per-task levy charged every time a company replaces a human with AI, forcing them to price in the demand they are destroying before they pull the trigger. No government has implemented this. No major economy is seriously discussing it. Meanwhile the numbers are already tracking the curve. 100,000 tech workers laid off in 2025. 92,000 more in the first months of 2026. Jack Dorsey fired half of Block's workforce and said publicly: "Within the next year, the majority of companies will reach the same conclusion." Nobody is doing anything wrong. Companies are following their incentives perfectly. That is exactly the problem. Rational behavior. At scale. Simultaneously. With no mechanism to stop it. Two economists built the math. The math leads to one place. Source: Falk & Tsoukalas · Wharton School + Boston University · arxiv.org/pdf/2603.20617



We have a choice: either tax the very rich more or have widespread extreme poverty





I think I've said this before, but it bears repeating. I've been described as a genius more than once, my IQ is in the nosebleed range, and I don't think there are any "magicians" in Hardy's sense, no mystical discontinuities. If Hardy had been bright enough, he would not have found Ramanujan's thought processes incomprehensible. I was thought to be a mathematical prodigy in my teens. I wouldn't have understood Ramanujan's thought processes in his day, and today I don't understand how Terence Tao's mind works. But I don't inflate my incomprehension into the conclusion that there is something ineffably bizarre about Ramanujan and Tao that is beyond the ken of mortals. I think this kind of mystification is deeply unhelpful, and I've never gotten over being irritated at Hardy for pushing it.
