>Modern Monetary Theory (MMT or Modern Money Theory) is a macroeconomic theory that sovereign governments have an unlimited financial ability to pay for the things they wish to purchase and to fulfill promised future payments. MMT claims that these governments also have an unlimited ability to provide funds to other sectors, and that because of this, it is not possible for a government that issues its own currency to be bankrupt
