The major glaring problem with MMT is that they don't communicate clearly. Public debt is a MAJOR problem when it's debt-based and interest-carrying, because then the Fed has to print more to cover the interest payments, which leads to price inflation, which is destroying the poor and middle class.
The better way: print debt-free -> invest solely in commons assets -> tax back and repeat. This would eliminate inflation and send widespread wellbeing soaring. As it stands, purchasing power and wellbeing are cratering, while money-printing and taxation enrich the hyper-elites with interest. Pure evil.
