Modern Monetary Theory

Here are key myths that Modern Monetary Theory (MMT) challenges, plus foundational concepts:

MythMMT PositionExplanation
Government budgets work like household budgetsGovernments are currency issuers, not usersUnlike households, sovereign governments can create their own currency and don't face the same budget constraints
Government debt burdens future generationsDebt is mostly owed to domestic holdersMost government debt is held domestically and represents private sector savings, not a burden
We need to balance the federal budgetDeficits can be beneficial and necessaryGovernment deficits inject money into the economy and can support full employment
Printing money always causes inflationInflation occurs when demand exceeds productive capacityMoney creation only causes inflation if it pushes the economy beyond its real resource limits
We need to "pay for" government spending with taxes firstSpending comes before taxation logicallyGovernments spend money into existence first, then taxes remove money from circulation
Social Security and Medicare are "going broke"These programs can't run out of moneyThe government can always fund these programs; the only limit is real resources, not money
Rising national debt will bankrupt the countrySovereign debt in own currency isn't bankruptcy riskCountries that issue their own currency cannot be forced into bankruptcy by debt denominated in that currency
We need foreign creditors to fund our governmentDomestic savings automatically fund government deficitsGovernment deficits create the very savings that appear to "fund" them
Austerity is necessary to restore fiscal healthAusterity often worsens economic conditionsCutting government spending during downturns typically prolongs recessions and increases unemployment
Monetary and fiscal policy should be separatedCoordination between treasury and central bank is naturalMMT sees monetary and fiscal policy as inherently linked aspects of government financial operations


MMT Core Concepts


ConceptDefinitionHow It Works
Sovereign MoneyCurrency issued by a government with monetary sovereigntyGovernment creates money by spending it into existence, not by borrowing or printing physical cash
Monetary SovereigntyControl over one's own currency and monetary policyRequires: own currency, floating exchange rate, no foreign currency debt
Value Creation - Tax AcceptanceMoney gets value because government requires it for tax paymentsTaxes create demand for the currency, giving it value and driving economic activity
Value Creation - Legal Tender LawsGovernment declares its currency must be accepted for debtsLegal framework enforces currency acceptance throughout the economy
Value Creation - Real ResourcesMoney's purchasing power depends on available goods/servicesValue ultimately tied to what the economy can actually produce and deliver
Fiat vs Commodity MoneyModern money is fiat (government decree), not backed by goldMoney is valuable because of government backing and social acceptance, not intrinsic worth
