The counter argument to MMT.
Thomas Sowell provides the takedown:
Thomas Sowell, a prominent free-market economist and critic of expansive government intervention, would likely reject core elements of Richard Murphy’s (and broader MMT) positions as ignoring fundamental economic realities like scarcity, incentives, unintended consequences, and the destructive effects of inflation.
Murphy’s MMT Position (Simplified)
Murphy describes MMT as explaining how sovereign currency-issuing governments (like the UK) actually operate: They spend by creating money (via the central bank), taxes withdraw money to manage demand and control inflation (not to “fund” spending), deficits create private-sector assets, and the real limit is inflation/resources rather than solvency. Governments face no inherent financial constraint like households and should prioritize full employment and public goals over balanced budgets or austerity.
Sowell’s Likely Counterarguments provide a clear framework for opposition. Key points:
1 Scarcity and Real Resource Constraints (Not Just Inflation):
Sowell emphasizes that economics begins with scarcity—there is never enough of everything to satisfy all wants. Government “creating money” to spend doesn’t create real resources (labor, materials, goods). It merely redistributes them, often inefficiently. MMT’s focus on inflation as the primary constraint downplays how printing/spending distorts prices, misallocates resources, and crowds out private uses. Sowell would argue this leads to waste, as politicians chase visible “needs” without trade-offs.
2 Inflation as a Hidden Tax and Destroyer of Wealth:
Sowell repeatedly calls inflation “the most universal tax of all” and “a way to take people’s wealth from them without having to openly raise taxes.” It erodes savings, punishes the prudent, transfers wealth to debtors (often government), and creates uncertainty. Historical examples like the Weimar Republic show massive money-financed spending leading to ruin, not prosperity. MMT’s willingness to run deficits and use taxes only reactively to curb inflation would strike him as dangerously naive—politicians rarely act in time, and inflation hits the poor and middle class hardest.
3Government Spending, Incentives, and Unintended Consequences:
Sowell is deeply skeptical of claims that more government spending “stimulates” or solves problems. He notes the assumption that spending more taxpayers’ (or printed) money improves outcomes survives endless evidence to the contrary. Expanded spending creates dependency, bureaucracies, and political incentives to buy votes rather than deliver value. MMT’s framing enables ever-larger deficits and programs without fiscal discipline, ignoring how interventions distort markets (e.g., via price signals).75
4False Analogy and Political Reality:
Sowell would likely call out the household-government analogy rejection but flip it: While governments can print, the real costs (opportunity, inflation, future burdens) remain. Politicians disregard scarcity; MMT gives them intellectual cover for short-term populism (“magic money tree”) at long-term expense. He favors reduced government spending overall, not clever accounting to justify more of it.
5Empirical and Historical Lens:
Sowell draws on evidence that market-driven coordination outperforms central planning or heavy fiscal activism. Post-WWII recoveries, stagflation in the 1970s, and failures of big-spending initiatives align with his views over MMT-style functional finance.
In short, Sowell would view Murphy’s MMT as sophisticated-sounding rhetoric that replaces what has worked (fiscal prudence, sound money, market incentives) with what sounds good (unlimited public spending without “financial” worry). It risks repeating historical mistakes where governments overreached monetarily, leading to inflation, inefficiency, and eroded prosperity.
