Economics: Weekly Summary (October 06-12, 2025)

Key trends, opinions and insights from personal blogs

I would describe this week in economics blogging as a noisy kitchen where everyone is frying different things at once. Some pots are sizzling hot — AI and data centers — and others are slowly simmering, like housing and wages. To me, it feels like a small town fair with a few carnival games rigged, a new band playing too loud, and an old man yelling about the price of bread. You get the idea. Here’s what I kept noticing, and why I think it’s worth poking around the original posts.

AI and the data-center boom: big promise, bigger questions

If there’s one theme that dominates this week, it’s AI infrastructure. You can’t walk five posts without tripping over the data-center debate. Some writers talk about a full-blown bubble. Others say it’s more complicated — like a late-stage industrial buildout with real, but risky, infrastructure value.

On the bubble side, several pieces sound the alarm. Aaron Brethorst writes about the clear parallels to the late-1990s fiber-optic boom. To me, that comparison lands hard. You remember the telecom blowup: shiny fiber, overbuilding, and then someone turns off the lights and the bills still come due. The worry with data centers is similar — lots of capital, rapid build, yet uncertain long-term demand. Jamie Lord adds to this with a sharp image: the economy’s growth made mostly of data-center investment looks like a monoculture farm. It grows well when conditions are right. It dies fast when a single blight shows up. That image stuck with me — monoculture is not just agricultural talk; it maps onto whole-country risk.

Then you have the counter-views or, at least, the shades of gray. Paul Kedrosky brings in Carlota Perez’s framework and says this might be an installation surge rather than pure folly. Perez would argue that infrastructure sometimes gets built ahead of productive use, and that’s not always useless. It creates platforms for later productivity. I’d say that argument comforts the optimists, and it’s not wrong. But it doesn’t erase the pain if the math is bad and cash runs out.

A few posts get into the messy day-to-day cash math. Quoth the Raven and Will Lockett both mention fears that financing around AI is shaky — banks and investors might not fully grasp the depreciation schedules, replacement cycles, and how rapidly hardware gets obsolete. Chamath Palihapitiya flags the large capital raises (xAI, et al.) that make GDP numbers look shiny right now. That point keeps popping up: headline GDP growth is being propped up by capex that could be ephemeral.

Then there’s the insider point-of-view wrinkle. Quoth the Raven (another piece) shares anecdotes from senior industry folks who are quietly puzzled by the AI project math. That felt like overhearing a lunch table conversation. The big firms keep spending. The smart folks inside are nervous. The public investors are clapping their hands.

A couple of other angles are fun and a little worrying. Alex Wilhelm and others note the market’s love affair with semiconductors. Semis, suddenly, look more valuable than software at some turns. That’s a big structural switch if it sticks. Ties into that are the OpenAI–AMD partnership chatter. Why would OpenAI want a piece of AMD? Supply security. Also, to me, it looks like someone wanting to own a bakery because the bread line is getting long.

If you’re curious and want the messy spreadsheets, go read Aaron Brethorst and Jamie Lord. They’ll give you the crunchy bits.

Wages, living standards, and the small print on inflation

Wages and real incomes keep showing up like a weather report you don’t like. Mike “Mish” Shedlock kicks off the week noting a long slide in real median annual wages since May 2021. He compares different inflation measures — PCE versus CPI — and points out something I kept thinking about: these indices miss stuff. Property taxes, tips, and other household-level costs sometimes get left out of the neat macro story. To me, that’s like calling a potluck complete when someone forgot the salt. Numbers look tidy at a distance. Up close, seasoning is missing.

That ties to public sentiment. Mike “Mish” Shedlock also flags polling showing nearly 70% of Americans think the economy’s on the wrong track. Seventy percent. That’s not a statistical quibble — it’s political weather. When most folks feel squeezed on prices and housing, politics reacts. You don’t need a PhD to see how this could shape elections and policies.

On the policy front, Davi Ottenheimer throws a dart at trickle-down theories. He highlights evidence that direct cash transfers to poor families produce measurable gains — lower infant mortality and local GDP boosts. To me, that’s sensible in a plain, slightly stubborn way: give money to those who will use it immediately for needs and local spending. It’s not rocket science. It’s groceries and medicine and a car that gets to work.

Meanwhile, immigration and the labor supply are debated too. Nominal News worries aloud about a proposed $100k H‑1B fee that could torpedo high-skilled immigration. The post lays out the long-term case that skilled immigrants don’t just take jobs; they create them and pull in investment. This is the opposite of the old scare story. If you cut skilled immigration, you shrink some of the economy’s pipelines.

Put those together — falling real wages, pessimistic polls, and potential limits on skilled immigration — and you get a picture where political moves around jobs and labor could amplify frustration. The blog posts made this feel quite human. Like watching a neighborhood where small shops close, and everyone eats more microwave dinners.

Housing: cronyism, rents, and the musical chairs of affordability

Housing kept showing up in interesting ways. Kevin Erdmann made a clear, almost stubborn point: rising rental value drives affordability problems more than mere interest-rate blather. He pushes back on the easy explanation that institutional investors or mortgages are the sole culprits. To me, that’s like watching a crowded bar and blaming the coat rack. The real squeeze might be who rents, who charges what, and who gets left standing when the music stops.

Carol Roth’s piece (via Kevin's notes) argues that regulation, cronyism, and zoning are big parts of the problem, and she offers typical conservative fixes like incentives for smaller homes and lower property taxes. I’d say her tone felt partisan and prescriptive, but there were concrete suggestions worth chewing on. The debate is not just policy wonkery. It’s people deciding whether they can afford a roof and a decent commute.

One follow-up post by Erdmann circles back to the rental angle. He repeats, a little — and that repetition helps — that rent is central. It’s not a minor note. Rent moves first; ownership numbers react later. If someone wants the short route to affordability, they should be looking at rent dynamics.

Geopolitics, tariffs, and rare earths — trade spats get expensive

This week also had trade fireworks. Mike “Mish” Shedlock covers a 100% additional tariff on China and export controls on key software. Stocks dipped. Bonds rallied. It’s classic: you smack tariffs on a trading partner, and financial markets adjust in real time. But the real story is supply chains. Chamath Palihapitiya and others note China's moves on heavy rare earth exports and controls. Those minerals matter to everything from semiconductors to green tech. If access gets restricted, the cost lines move and fast.

Then there’s Taiwan. Judy Lin 林昭儀 reports President Lai’s push for major industrial and defense spending. Taiwan is saying, bluntly, that chips and industrial policy are national security. They’re putting money behind that line. That’s a neat mirror to the US political conversations about industrial subsidies and state capitalism. It’s not just economics; it’s geopolitics wearing an economic coat.

Add to that Alex Wilhelm's pieces on the shifting value between semiconductors and software, plus debates around national investment in critical metals, and you get a geopolitical stew. The takeaway: supply chains are no longer a quiet finance issue. They’re policy fireworks.

Markets, gold, and the ‘blowoff top’ mood

Markets are weird this week. Quoth the Raven warns of a speculative frenzy, even quoting Paul Tudor Jones for color. Will Lockett and Alex Wilhelm note that while big tech and AI buzz pump indices, safe-haven flows and commodity moves tell another story. Gold smashing $4,000 an ounce, in one writeup from Quoth the Raven, feels like a canary in the coal mine. People buy gold when they think the map is unreliable.

There’s also the social psychology piece: a lot of chatter sounds like the late-1990s, where valuations outpaced economic reality. One post uses the phrase “blowoff top” — that jolts you. It’s the kind of phrase traders whisper when they can’t tell whether the party ends tonight or in a messy week.

Government shutdown, data blackouts, and the private-data pivot

Several writers point out something dull and important: the US government shutdown messes with data. Fractal Market Cycles and Regimes notes that non-essential services, including some economic data collection, pause during shutdowns. That makes official statistics less timely and sometimes biased. People lean on private data instead.

That shift is interesting. Private providers like Markit (PMI) get spotlighted for timeliness and being less politically clogged. But private data brings its own biases — coverage choices, business models, and client lists. It’s a shift from a single, messy official scoreboard to a patchwork of private scoreboards. It’s like switching from a town hall bell to a dozen smartphone apps telling you when the bus might show up.

Politics and governance: the authoritarian drift and public mood

Politics and economics braided through many posts. Naked Capitalism’s pieces (several this week) lay out worries about authoritarian tendencies, Milei’s meltdown in Argentina, and the US political landscape turning sharp and sometimes alarming. Naked Capitalism writes about Milei’s chaos and other global political noise. That’s not an economic footnote — political instability feeds economic distress.

There’s also a sharp piece about plenary power by AmericanCitizen. It’s a short, pointed reminder: centralizing authority without constraints is a money-and-rights problem. History has a nasty habit of repeating itself.

Tom Neuburger’s piece — via Naked Capitalism — asks whether some political actors are stoking domestic conflict. It’s dramatic, sure, but that drama matters for markets and investment. People don’t commit capital when the future looks like the script of a bad movie.

Social commentary: the decay metaphor and small-scale fixes

Some posts get less macro and more literary. indi.ca likens the American economy to a dead fly being dragged around — vivid if a touch grotesque. Chris Arnade muses about banker identities and the strange marriage of self-worth to profit. Rachdele laments ‘band-aid’ solutions that patch society without fixing core design faults.

These pieces matter because they’re not numbers. They’re feelings and frames. They help explain why people reject simple policy fixes. They help explain the stubbornness of public moods.

Practical economics: airport timing and cash-use fights

On the lighter end, Gad Allon made me rethink airport routines. He uses the newsvendor model to argue the two-hour rule is often overkill. If TSA waits are usually under 20 minutes, the two-hour mantra looks expensive in time lost — a hidden $83 billion yearly bill for U.S. travelers, according to his arithmetic. That’s the sort of practical economics I like. It’s small, but it nudges behavior. It’s the kind of thing you might tell your friend who is always at the airport two hours early.

Then Brett Scott’s post on resisting a cashless society is a different practical push. He lists reasons people should hang on to cash — surveillance, exclusion, payment censorship risks. It’s a civil-liberties flavor of economics that matters more as payments go digital. If you live in a place where the electricity can cut and your card stops working, you’ll suddenly care about paper money. That’s the everyday angle.

Health, demographics, and the long game

A few posts looked farther out. Scott Sumner wrote on global fertility decline and why the common fixes are shallow. He says the opportunity cost of kids — time, money, lifestyle — is a big part of the story. That’s not a short-term economic lever. It’s cultural and structural.

Then there were historical takes like Nathan Knopp on pandemics and economies. He uses Rome as a grim case study, arguing that plagues exacerbate economic decline. With COVID still in memory, that linkage feels painfully relevant. If you think pandemics are only a public-health fight, these posts remind you there are deep economic echoes.

Odd corners and curios: board games, Nobel prizes, and millionaire babies

Not everything was doom-and-gloom. Weekly Filet offered tidy distractions: a board game from the Planet Money folks, Sigur Rós concert notes, and a long list of curiosities. Chamath’s weekly runs through Nobel winners and the rare-earth moves. These pieces are like the side dishes at a roast. They don’t drive the meal, but they make it richer.

There’s also a piece about declining fertility framed as the ‘billionaire baby boom’ by Scott Sumner. He argues wealthier people’s choices, and broader economic incentives, produce demographic shifts. It’s a mix of sociology and economics, with a dash of moral hazard.

Recurring disagreements and where people mostly agree

A few patterns in the debate are worth flagging, because they repeat.

  • Data centers and AI investments: most authors agree something big is happening. They disagree sharply on whether it’s a productive buildout or an unsustainable bubble. Optimists invoke long-term platform effects (Perez-style). Pessimists point to financing, depreciation, and concentration risks.

  • Measurement and mood: many posts stress that headline GDP and corporate profits mask how people actually feel. Real wages down, polls bad, and gold up — that trio keeps showing up. Authors agree the official metrics can mislead. They differ on what to do about it.

  • Housing: writers mostly agree rent matters. They split on causes and solutions. Some blame regulation and cronyism. Others point to structural forces and investor dynamics. But rent keeps being the center of the map.

  • Geopolitics and supply chains: many bloggers see trade moves — tariffs and rare-earth controls — as potentially big shocks. There’s common agreement these are not minor skirmishes. They can reshape industry economics.

  • Social safety nets: a small but loud set of posts argue for direct transfers as effective tools, and they use data to back that up. Those posts challenge trickle-down lore.

What I’d poke next (if you like curiosity and a little unease)

If you want to dig deeper, I’d start with the posts that combine quantitative worry with narrative color. Read Aaron Brethorst and Jamie Lord on the data-center risks. Then read Paul Kedrosky for the Perez lens to get the other side. For the lived-economy angle, Mike “Mish” Shedlock on wages and polls and Davi Ottenheimer on cash transfers give you the human-impact side.

The airport-newsvendor note from Gad Allon is a neat, immediate read. Brett Scott’s piece on cash is the civil-liberties head-slap you didn’t know you needed. And if you want a sense of markets’ mood, a couple of reads from Quoth the Raven will do it.

It’s a busy week. It feels like seeing a lot of good maps, but from different cartographers. Some maps draw a city. Others draw a country. Few draw the full archipelago. If you’re curious, dig into the original posts. They’re where the charts, the spreadsheets, and the cranky asides live.

That’s enough for now. If you want, I can pull a short reading list. Or I can sketch a simple checklist for what would collapse a data-center-led GDP: think demand shortfall, rising financing costs, and faster-than-expected obsolescence. Or — and here’s a tangent — I could compare the current feel to an overbooked diner: everyone in line thinks dinner is going to be amazing, the cook is tired, and the health inspector is on a break. Either way, the kettle’s whistling. Read the posts. See what you think.
