That under the MMT system the government would spend "fiat money" because taxes would be used to curb inflation instead of government expenditures and a "guaranteed-job" program would be created so everyone that is willing and able to work will work. Obviously the government just spending money would result in inflation but the taxes now collected would be used to curb inflation and the new jobs would balance it out as well because an increased level of production and consumption. My partner and I are thinking of running this as a K, Cap bad then the alt as MMT, then have a CP that says do plan but in the world of the alt. So essentially, the K's Net Benefit is the CP. We would say they could never truly get econ growth in the squo, yet MMT gives econ growth.
There is a link that explains MMT pretty well
