“Keynes vs MMT: Whose Economic Theory Fits Our World?” — A Māori Green Lantern Analysis - 23 November 2025

The confrontation between Keynesianism and Modern Monetary Theory (MMT) is not just a technical debate, but a struggle over narratives that shape who benefits and who is harmed by economic management. Both theories reject the neoliberal dogma of markets as ungoverned forces, yet their differences expose how policy tools become weapons—used for austerity, accumulation by a few, or redistribution. As Richard Murphy’s analysis reveals, the choice between these frameworks determines whether governments serve financial elites or the collective wellbeing of their people.

Naming the antagonists matters—from City of London financiers who demand government obedience, to neoliberal politicians (National, ACT in Aotearoa; Conservatives in the UK) who champion budget cuts over Māori, Pacific, and working class survival. This essay grounds analysis in whakapapa and verified sources, following Māori Green Lantern kaupapa:

every claim is evidenced, connections traced, and harms quantified.

Historical Context: From Keynes to the Fiat World

Keynesian economics emerges from the crisis of the 1930s, the gold standard, and the mass unemployment of the Great Depression. John Maynard Keynes’s 1936 General Theory disrupts the notion that markets self-correct for full employment; instead, Keynes saw the state as a necessary intervener. Yet, Keynes’s worldview is shaped by gold-standard constraints—governments borrowing in slumps, repaying in booms, with balanced budgets as the holy grail.

Modern Monetary Theory, in contrast, materialises in the fiat currency world of the 1990s. Gold is gone, and governments are currency issuers rather than currency users—they can’t run out of money in their own currency. MMT theorists such as Mosler, Wray, and Kelton reconceptualise government spending as the engine of money creation, with taxation as the tool to withdraw purchasing power and control inflation—not to “fund” spending.

Who Benefits? Neoliberalism, with its “government-as-household” analogy, serves financial elites by producing fear, austerity, and mass precarity. Māori, Pasifika, workers, and indigenous whenua bear the real costs, while the property-owning and financial sectors profit.

Deconstruction: Māori Mātauranga Meets Western Economics

Drawing on mātauranga Māori, the following analysis exposes the mauri-draining consequences of policies constructed on market dogma, and quantifies harm through critical comparison.

The Core Differences

Keynesianism still treats money as the constraint, assuming governments must borrow from scarce financial markets before they can spend. This gold-standard mindset persists despite fiat currencies making it obsolete. MMT recognises that governments create money when they spend, with the only real constraint being the availability of real resources—workers, materials, productive capacity—not money itself.

Analysis: Five Hidden Revelations (All Verified)

1. “Debt” is a Mythical Burden — MMT Shows It’s Actually Savings

MMT explodes the myth pushed by neoliberal and Keynesian politicians that government debt is a burden for future generations. In reality, public debt simply records the private sector’s desire to save with the government: bonds are savings accounts, not liabilities. The UK’s persistent “surpluses” are a fiction—since WWII, budgets rarely balance.

The cost of austerity is borne by social services, Māori health, housing, and education. As Te Ara documents, government economic policies greatly increased unemployment in the 1980s and 1990s, with Māori suffering disproportionately. Full employment is never the goal—fear of debt makes workers expendable.

2. Inflation Management: Neoliberal Fallacies Enable Harm

Keynesian inflation paranoia legitimised cuts and wage repression, turning “full employment” into a taboo. MMT shows governments should push for full employment and only tax excessively if the real economy overheats. Inflation management is about balancing output, not penalising growth.

City financiers, the IMF, and neoliberal bureaucrats gain power over government decisions by threatening inflation scares. According to Stats NZ data, Māori unemployment peaked at 13.7% in 2010 and remained above 11% through 2016—the austerity era—while being told governments “couldn’t afford” to invest in jobs.

3. Household Analogy: Policy Weaponised Against the Vulnerable

“Government-as-household” framing—treating a sovereign nation like your personal bank account—is a fallacy weaponised by neoliberal parties to justify benefit cuts and asset sales. This household metaphor obscures the fundamental truth: governments create money; households don’t.

Public hospitals, Māori land trusts, and schools suffer when “deficits” are treated like family debt, despite governments being money creators.

4. Full Employment: Deficit as Surplus

MMT reframes deficits as private sector surpluses: every government “deficit” is the public’s net savings. Sectoral balances data from Wynne Godley shows that persistent surpluses are never achieved—deficits are normal; surpluses hurt the real economy.

Austerity, by this light, is simply wealth extraction from ordinary people to financial elites.

5. Mauri-Depleting Policies: Who Suffers Most?

Neoliberal austerity, justified by Keynesian fear-mongering, depletes the mauri (life force) of iwi and hapū by cutting resources while Māori suffer disproportionate unemployment. The Waitangi Tribunal found that reparations for past losses were more urgent because government economic policies had greatly increased unemployment, with Māori suffering disproportionately.

UK austerity policies from 2010 onwards weakened the NHS before the pandemic, with the public health grant cut by 28% in real terms since 2015-16. Every cut justified by “debt” increases chronic illness, suicide risk, and intergenerational harm for Māori due to blocked opportunity and loss of land.

Implications: Quantifying Harm, Action Pathways

This chart shows how Māori unemployment consistently exceeds the national average, with the gap widening significantly during austerity periods (2010-2013) when Māori unemployment peaked above 13%. Data sourced from Stats NZ and Figure.nz verified sources

The data reveals the brutal reality: Māori unemployment consistently exceeds the national average by 3-7 percentage points throughout the austerity period. During the worst years (2010-2013), when neoliberal governments claimed they “couldn’t afford” job creation, Māori unemployment soared above 13% while being lectured about “fiscal responsibility.”

UK data shows that austerity policies generated spikes in poverty, housing insecurity, and lower life expectancy. Māori, Pacific, and POC communities face higher unemployment, incarceration, and poor health in budget-cut cycles.

A switch to MMT framing would enable robust investment in jobs, marae, public services, and climate adaptation without the fictional constraint of “balanced budgets.” MMT’s Job Guarantee proposal offers a pathway to genuine full employment and price stability—targeting both goals simultaneously, rather than sacrificing workers to appease inflation fears.

Rangatiratanga as Economic Justice

The evidence is overwhelming: Keynesian and neoliberal dogma empower elites, entrench austerity, and mauri depletion. MMT, when properly understood, enables governments to serve the collective, uplift Māori, and restore whānau wellbeing by prioritising real economy output, not financial optics. Economic sovereignty (rangatiratanga) demands rejecting false deficit panics and naming every harm, every benefit, and every power structure for what it is.

Name the agents of austerity. Demand data. Restore mauri.
