Modern monetary theory
A macroeconomic concept that purports monetarily sovereign countries can create/print money to fund spending programs, as opposed to issuing debt. MMT further postulates that governments can fund agendas like climate change, income inequality, universal healthcare, basic income, and unlimited immigration by simply printing the money necessary to fund the associated programs.
According to MMT, national debt is not a concern since government can create (print) new money by which to pay outlays and interest.
