Government Deficit = Private Surplus

An accounting identity stating that government sector deficits equal non-government sector surpluses, meaning every dollar of government deficit spending becomes a dollar of private sector financial assets.

This relationship is a fundamental accounting identity in MMT, not an opinion or theory. When government spends $100 billion more than it taxes, that exact $100 billion ends up somewhere in the private sector - as household savings, business profits, or bank reserves. As Stephanie Kelton notes, every deficit is good for someone because on the other side of government red ink is somebody else's financial surplus. This challenges conventional deficit fears by showing that government deficits don't drain resources from the private sector - they add financial assets to it. The key policy question becomes not whether deficits are bad, but rather 'deficits for whom and for what purpose?' This sectoral balance relationship is crucial for understanding how fiscal policy affects private wealth and why deficit spending can stimulate economic growth.

"Government deficits steal money from future generations" - Government deficits actually create financial assets for the private sector today; the 'debt' is simply the record of money the government has spent into existence.

"Deficits always cause inflation" - Deficits only cause inflation if they push spending beyond the economy's productive capacity; when there are unemployed resources, deficits can boost output without raising prices.

"Government must balance its budget like a household" - Unlike households, governments that issue their own currency can never run out of money; their deficits become the private sector's financial wealth.
