Key Takeaways

  • Factory Cost Structure Reality: Empirical surveys since the 1930s consistently show manufacturers operate at 70-80% capacity with falling per-unit costs as output increases, directly contradicting the diminishing marginal productivity assumption that underlies both Austrian and neoclassical supply curve theory used in policy decisions.
  • Money Creation Mechanics: Money functions as a three-party promise system involving buyer, seller, and bank rather than commodity barter. Private banks create money through lending (loans create deposits), while government deficits inject liquidity by spending more than taxing, with no gold backing required for modern monetary systems.
  • Sectoral Financial Balance Requirements: Banks must maintain positive equity to function, mathematically forcing the combined private and government sectors into negative equity. Government deficits of roughly 20-25% of GDP create the negative government equity that enables private sector positive net worth, preventing perpetual household indebtedness.
  • World War Two Monetary Lessons: Beardsley Ruml's 1946 paper documented how wartime production was financed through direct money creation, not borrowing, proving governments create money through spending. Neoclassical economists spent subsequent decades erasing this understanding, creating current debates about government debt that were empirically settled eighty years ago.
  • Equilibrium Theory Failures: The obsession with supply-demand equilibrium curves ignores capitalism's defining characteristic of constant evolutionary change through product differentiation and competitive dynamics. Real markets involve firms with excess capacity targeting known rivals through innovation, not homogeneous products reaching price equilibrium points.

What It Covers

Economist Steve Keen challenges mainstream economic theory, arguing both neoclassical and Austrian schools misunderstand money creation, factory production costs, and capitalism's fundamental mechanics. He demonstrates how government deficits enable private sector financial health through integrated accounting models.

Notable Moment

Keen reveals that removing government from the financial system mathematically forces the private sector into permanent negative equity relative to banks. Using his Ravel accounting software, he demonstrates the private sector would perpetually owe banks more than banks owe them without government deficit spending creating offsetting positive equity.

Episode Transcript

Economists get away with this garbage, and it is garbage in my opinion, because you don't need the economist to have an economy. The economy is something which exists independent of economists. That doesn't apply to engineering. Without engineers, you don't have engineered products. So economists effectively have no skin in the game to use Taleb's phrase they can say whatever they like and still be taken seriously if they get inside the mind of a politician and that's where economics turns into ideology This show is brought to you by my lead sponsor, Ayran, the AI cloud for the next big thing.

How long ago since we last talked? I'm gonna say it was very early when I did the podcast. I'm gonna say seven or eight years. Okay. Okay. Yeah. A long time ago. And you know what? Funny enough, that show still, does really well. Oh, okay. You're you're you're a good guest to have for Google. It's, lived well, but, I'm glad we're doing it in person. Mhmm. And, you know, the show is very different now. I deeply care about two things right now, economics and politics and the cross section of the two. Yeah. Yeah. And therefore, the future of this country. Mhmm. I think about it a lot. And so it's good to talk to you again. I've obviously, been entrenched into the Austrian school quite a bit. Of course. Yeah. Yeah. And, I'm sure we'll have things we agree or disagree on that. But really, I'm just more interested in in you and what you talk about. Why does economics matter? Oh, economics is the description of the the way in which our social system functions. So if you wanna know how it functions, you've gotta know economics, but the question is, does economics actually fulfill its task? In my opinion at the moment, no, it does not. It just we have a whole range of competing schools of thought about how the economy operates, all of which talk past each other, and that's standard for competing paradigms in virtually any discipline. But the reality is most of our decision making about how we should change the economy to make it work better works from what I can fundamentally prove in myths. And therefore, if you kind of this is the the fundamental guiding principle for me is you can't reform what you don't understand. And And that's what I find is the nature of economics. Would would economics work better without politics? It'd work better without economists, frankly. I I think it's, I mean, the extent to which economists have clouded the theory of …
