Tim Worstall has a post decrying the dangers of MMT ever being used in the real world—even as he recognizes or at least suggests that it might be the correct description of how the monetary system works—and is particularly concerned about Stephanie Kelton’s new appointment as Chief Economist on the Senate Budget Committee. (Note: Randy Wray also posted a critique of Mr. Worstall’s post today.)
Mr. Worstall’s main issue is one we’ve heard hundreds of times before—because MMT explains that currency-issuing governments operating under flexible exchange rates and without debt in a foreign currency do not actually have budget constraints, this opens the door to all sorts of problems if put into practice. We can’t trust our government with this information, in other words—it must be required to match spending with revenues over some period (whether each year, over the business cycle, etc.) or at least plan over some period of time to not allow the debt ratio to rise beyond a modest level.**
