Martin Wolf uses MMT language in describing the zero sum game that is being played out to devastating effect..
….These are mirror images: if the private sector runs a financial surplus (an excess of income over spending), there has to be either a fiscal deficit or a current account surplus (or both). The bigger the private surplus, the bigger the fiscal deficit or current account surplus must be. If, in reverse, fiscal deficits are to fall, the private sector must spend more relative to income or the current account must improve. Evidently, this needs to happen with higher spending, not lower incomes, particularly after a deep recession. (link to article)
