A government that issues its own non-convertible currency and borrows in it cannot involuntarily run out of money, so the binding constraint on its spending is the economy's real productive capacity. When spending pushes demand beyond available labor, materials, and capacity, the result is inflation, and inflation is the signal to pull back.
Through sectoral balances accounting, one sector's deficit is necessarily another sector's surplus: a government deficit adds net financial assets to the non-government sector, dollar for dollar. The identity itself is uncontroversial; what it implies for policy is the disputed part.
The book reverses the household model of taxing to spend: the currency issuer spends new money into existence first, and taxation later removes some of it from circulation. Taxes therefore serve to create demand for the currency, curb inflation by withdrawing purchasing power, redistribute income, and discourage particular behaviors, rather than to fund the government.
Treasury securities are described as a savings account version of currency: selling bonds swaps non-interest-bearing reserves for interest-bearing ones rather than raising funds the government lacks. The so-called national debt is therefore the historical record of dollars issued and not yet taxed back, held as private wealth, and it will not bankrupt a sovereign issuer or 'burden grandchildren' as the popular story says.
The government offers a public-service job at a fixed wage to anyone who wants one, creating a buffer stock of employed labor that grows in recessions and shrinks in booms. This replaces unemployment as the tool for disciplining inflation, anchors a wage floor, and keeps workers' skills intact.
Instead of asking whether a budget balances, ask whether it achieves full employment, stable prices, and adequate public goods using the resources available. Under this 'people's budget' view, the real deficits are unmet needs in jobs, health care, infrastructure, and climate, while a fiscal deficit is merely an accounting outcome. Proposals are evaluated by an inflation-risk budget that identifies which real resources they would draw on and how to offset excess demand, rather than by whether new spending is 'paid for' with revenue.
