So Modern Monetary Theory says that governments can NEVER, EVER spend too much money eh? France, Greece, Portugal, Spain should hire you to enlighten them. Too bad you weren't around when pre WWII Germany had 3500% inflation. You probably would have told them to keep spending too. Well, I wasn't smart enough to study Modern Monetary Theory so I had to study physics where I learned that you can't get blood from a stone. By the way, what's the net present value of the $100+ Trillion in unfunded obligations we have to Social Security, Medicare and Medicaid that come due before mid-century?
