MMT = Plain Chartalism

_{¡Watchout! sounds kinda similar to charlatanism, but it's not.}

Modern Monetary Theory (MMT) is a heterodox macroeconomic framework that says monetarily sovereign countries like the U.S., U.K., Japan and Canada are not operationally constrained by revenues when it comes to federal government spending. In other words, such governments do not need taxes or borrowing for spending since they can print as much as they need and are the monopoly issuers of the currency.
