Let me see, MMT is the acknowledgement that the government can spend the money it prints to make things happen in the economy and its only constraint is inflation which will, theoretically, not be triggered as long as there is slack in the economy. Quantative Easing on the other hand, in all its various forms and disguises, is the Fed pushing tons of money into the hands of bankers and then almost immediately the money is in the hands of traders and speculators who push up the price of assets for the purpose of price appreciation and not for productive activity. So when a lot of money is borrowed and given to bankers and speculators as a way to help them manage their bad debts and encourage nonproductive economic activity this is an action that is encouraged as necessary by the political and financial authorities. When more or less the same action is suggestted for ordinary people in the form of MMT then it is the irresponsible ruination of the economy.
