Setting the stage: Marx, profit rates, and why economics matters
Lex introduces Steve Keen as a critic of mainstream economics with deep interest in Marx, Keynes, Schumpeter, and Minsky. Keen frames Marx’s politics as rooted in an economic prediction: a falling profit rate would intensify exploitation and provoke revolution.
- •Lex’s overview of Keen’s approach: integrate ideas across economic traditions
- •Keen’s opening thesis: Marx’s political vision depends on the ‘tendency of the rate of profit to fall’
- •Revolution expected first in advanced economies (Marx) vs Russia’s path (Mensheviks vs Bolsheviks)
- 1:34 – 4:50
What economics should be: civilization, energy, and systems thinking
Keen defines economics as the study of how civilization is created and sustained—fundamentally grounded in energy and the biosphere. He argues modern economics has the ‘right name and wrong soul,’ failing to model reality as an evolving complex system.
- •Economics should explain how civilization rises above Earth’s baseline energy/consumption levels
- •Energy sources (sun, fossil fuels, nuclear) as the physical foundation of civilization
- •Economics’ role in ecological degradation and existential risk
- •Respect for life and the biosphere as a necessary ethical frame
- 4:50 – 8:33
Why mainstream tools fail: equilibrium obsession and the wrong mathematics
Keen criticizes standard economic modeling for relying on inappropriate mathematics and an equilibrium worldview. He argues that aggregate economies should be modeled with differential equations, stability analysis, and complex-systems tools—closer to engineering than textbook economics.
- •Difference equations vs differential equations for aggregate dynamics
- •Economists’ equilibrium assumptions without stability analysis
- •Complexity: economy, biosphere, and mind as intertwined systems
- •Call for systems engineering methods (stocks, flows, feedback loops)
- 8:33 – 23:28
A whirlwind history of economic schools: physiocrats to neoclassicals to Keynes
Keen walks through major schools of thought, emphasizing how value theory and assumptions about equilibrium changed over time. He highlights how neoclassical economics became dominant by shifting to subjective value and marginal analysis while sidelining money and instability.
- •Physiocrats: wealth from land/solar energy; manufacturing as ‘sterile’
- •Classicals (Smith/Ricardo): labor and objective cost-based value
- •Marx as classical tradition turned into capitalism’s critique
- •Neoclassical economics: marginal utility, marginal cost, equilibrium, and barter-like thinking
- •Keynes/post-Keynesians: uncertainty, volatility, and non-equilibrium dynamics
- 23:28 – 33:09
Money is not a veil: banks, accounting, and Modern Monetary Theory (MMT)
Keen explains money as a social relation formalized through double-entry bookkeeping—not a commodity like gold. He describes how banks create money via lending, how government deficits create private-sector money, and why treating money as irrelevant leads economics astray.
- •Double-entry bookkeeping: assets, liabilities, equity; transactions recorded twice
- •Bank lending creates deposits (money creation) alongside loan assets
- •Government deficits add net financial assets to the private sector (via banking reserves)
- •Money as a triangular relation: buyer, seller, and bank (Graziani’s ‘monetary theory of production’)
- •MMT framed as ‘do the accounting correctly’
- 33:09 – 51:23
Why Marx is brilliant: dialectics, foreground/background, and commodities
Keen praises Marx’s intellect and explains Marx’s dialectical method as a philosophy of change, not the simplistic ‘thesis-antithesis-synthesis’ trope. Marx’s key move is to analyze capitalism via the commodity—split between exchange value and use value—and the tensions that follow.
- •Marx’s ambition: a ‘critical examination of everything existing’
- •Dialectics as change via tensions (foreground/background), not Fichte’s triad
- •Humans reduced to ‘workers’ in capitalism: capacity to work foregrounded, humanity backgrounded
- •Commodity as capitalism’s ‘essential unity’: exchange value vs use value
- •Marx’s integration of objective and subjective layers (especially when humans enter the analysis)
- 51:23 – 1:08:19
Labor theory of value, use vs exchange value, and Keen’s critique: machines matter
The conversation drills into what ‘value’ means and how Marx differs from neoclassical utility theory. Keen argues Marx made a pivotal mistake by denying that machines can generate surplus, even though Marx’s own use/exchange value logic can be applied to machinery.
- •Value as contested: subjective (neoclassical) vs objective (classical/Marxist)
- •Marginal utility vs objective utility; why neoclassical pricing stories misfit factory capitalism
- •Marx’s ‘surplus value’ logic: buy labor at subsistence, extract longer working time
- •Keen’s key critique: the same surplus logic applies to machines (exchange value vs productive contribution)
- •Marx’s internal contradiction (Grundrisse insight vs later claims in Capital)
- 1:08:19 – 1:11:09
From Marxian economics to Marxist politics: why ‘profit must fall’ drives revolution
Keen distinguishes Marx’s economic framework from the political ideology built on top of it. Marx tried to argue socialism must arrive (not merely should) because falling profit rates would intensify exploitation, trigger revolt, and force systemic transition.
- •Marx’s political prediction rests on the ‘tendency of the rate of profit to fall’
- •Utopian socialists vs Marx: ‘should’ vs ‘must’ socialism
- •Marx’s utopian elements: human flourishing beyond specialized roles
- •Keen’s view: Marx’s political conclusions fail if machines also contribute to surplus
- •Transition expectations: revolution in advanced economies, not ‘primitive’ ones
- 1:11:09 – 1:13:28
What socialism means (and doesn’t): ownership vs control, and why definitions get weaponized
Keen clarifies socialism as public ownership of the means of production, distinguishing it from welfare-state policies often labeled ‘socialist’ in US discourse. He also contrasts socialism with fascism as private ownership under state direction, emphasizing the importance of ownership structures.
- •US political rhetoric vs technical meaning of socialism
- •Socialism: state/public ownership of the means of production and central planning
- •Means of production: factories, machinery, land (collective farms)
- •Fascism/Nazism: state direction with private profits (control vs ownership)
- •Why terminological confusion distorts debate
- 1:13:28 – 1:26:15
Why the Soviet model failed: Kornai, shortage economies, and the innovation problem
Drawing on János Kornai, Keen argues centrally planned economies become resource-constrained shortage systems that discourage innovation. The imperative to meet plan targets and allocate scarce inputs pushes producers to repeat last year’s output rather than take risks, leading to stagnation and dissatisfaction.
- •Kornai’s frame: resource-constrained socialism vs demand-constrained capitalism
- •Innovation vs repetition: why shortages make change costly and dangerous
- •Personal example: Soviet ‘Cossack’ motorbike as decades-old BMW design
- •Feldman’s growth logic: build capital goods first—but it hits labor/resource ceilings
- •Why consumers in the East envied Western variety and abundance
- 1:26:15 – 1:39:32
From central planning to central repression: Stalinism, incentives, and the loss of agency
Lex presses on how Marxist ideas can lead to dictatorship and atrocities. Keen argues that persistent shortages and dissatisfaction in centrally planned systems create incentives for suppression, while weak individual motivation (‘they pretend to pay us…’) corrodes productivity and culture.
- •Link from unhappy populations to coercive control in shortage economies
- •Worker motivation and productivity under chronic shortages
- •Cuba anecdote: low incentives and talent misallocation (chemist becomes taxi driver)
- •Anarchism aside: coordination problems without governance structures
- •‘Freedom’ as lived experience vs rhetorical slogan
- 1:39:32 – 1:59:23
China’s hybrid: economic decentralization with political centralization
Keen describes China’s post-Mao shift as pragmatic: loosen economic control to enable production, competition, and innovation while maintaining centralized political authority. He credits policy mechanisms (joint ventures, technology transfer) and engineering competence in state capacity, while noting risks of personality cults and over-compliance.
- •Deng Xiaoping pragmatism: ‘black cat/white cat’ as results-first policy
- •Free trade zones and forced partnerships: building domestic capitalist capacity
- •Political centralization + diversified economic control as the core hybrid
- •Benefits: infrastructure, high-speed rail, rapid industrial scaling, respect for engineers
- •Risks: censorship boundaries, bureaucracy ‘over-implementing’ directives, cult-of-leader dynamics
- 1:59:23 – 2:21:18
Climate change vs economic modeling: why Keen calls the mainstream view dangerously wrong
Keen argues many economic assessments of climate damages are built on unrealistic assumptions and omit key variables like precipitation. He focuses on systemic risks: destabilized weather patterns can collapse agricultural suitability, triggering geopolitical conflict and civilizational fragility far beyond GDP tweaks.
- •Critique of Nordhaus-style reasoning: ‘a roof protects you from climate change’ logic
- •Economists’ integrated assessment models omitting precipitation and system breakdowns
- •Climate as a shift in global circulation patterns, not just local temperature changes
- •Food production collapse scenarios (e.g., wheat suitability shrinking under AMOC disruption)
- •Innovation timelines: prototypes vs mass deployment at civilization scale
- 2:21:18 – 3:31:01
Economics meets politics and ethics: governance for complex systems, life, and the Minsky approach
The discussion turns to what political and economic governance could look like in a world constrained by ecology and complexity. Keen argues for humility, systemic modeling, and safeguarding large parts of the biosphere, then explains his Minsky software as a systems-dynamics tool that embeds accounting (Godley tables) to model financial macro-dynamics and instability.
- •Humans as one species among millions: governance must respect non-human life
- •Reserving large parts of Earth from human exploitation (E.O. Wilson ‘half-earth’ vs Keen’s stricter view)
- •Centralization vs decentralization under systemic crises (pandemics, climate)
- •Minsky software: system dynamics (Forrester) + double-entry accounting (Godley tables)
- •From Goodwin cycles to Minsky-style financial instability: debt, wages, employment, and chaotic dynamics
