The United States government is, yet again, facing a budget crisis. Government funding is set to expire on December 3, 2021 and Congress has a deadline of December 15 to raise the debt ceiling. Otherwise, the U.S. will default on its debts, and a worldwide financial collapse becomes a possibility.
Modern Monetary Theory (MMT) is part of the reason these crises — not to mention inflation — are becoming more common. It theorizes that because modern states control currency and have the power to levy taxes, they can print as much money as they want.
