MMT is two things: an accurate description of the status quo, and policy proposals based on that description. The descriptive part goes like this: A monetarily sovereign (currency producing) State doesn’t need tax revenue. It creates the money. The purpose of taxation is to coerce at least some people to need the money, putting them in a state of “unemployment” where the State can pay them in otherwise worthless fiat for their labor. The policy proposal goes like this: Since the State compels people to labor, it is obligated to provide jobs to anyone who wants one. To MMTers, it’s moral to compel labor via taxation, but immoral to tax without providing a job to pay it. The real tragedy to me is that MMT correctly identified the State as a slaver and fiat as blood money, but they’re just like “lol OK”. It helps their cognitive dissonance that they use friendly language to describe the despicable state of affairs. They call this whole proceeds of slave labor by fiat “moving resources from the private to the public sector” or “the State provisioning itself”. Warren Mosler, founder of MMT, explains this process using an allegory.
