MMT claims to be the legitimate heir to the theories of Britain’s John Maynard Keynes, who created the field of macroeconomics during the Great Depression. Keynes coined the term “paradox of thrift.” His insight was that while any single household can dig itself out of a hole by cutting spending when its income falls, the economy as a whole cannot. One household’s spending is another’s income, so if everybody cuts back, no one gets paid. What you get then is a depression—a situation only government can fix because, unlike the private sector, it can afford to spend freely, putting money in people’s pockets and thus getting the economy back on track.
